A spherical body made of high specific acoustic impedance material, such as tungsten carbide, is positioned a given distance from a source/receiver transducer which is energized to produce a short acoustic pulse directed toward the sphere. Acoustic signals reflected from the sphere are detected by the transducer and processed in the time domain to separate the rigid portion of the return from the elastic portions. The rigid portion is corrected for the transducer to sphere distance, the reflectivity of the sphere, and for the radius of the sphere. The resultant corrected signal represents the incident acoustic pulse produced by the transducer.申请人:THE UNITED STATES OF AMERICA AS REPRESENTED BY THE SECRETARY OF THE NAVY代理人:Robert F.

calibrationCalibration: A Guide to Accurate MeasurementIntroductionCalibration plays a crucial role in ensuring accurate measurements across various fields and industries. Whether it is in laboratories, manufacturing facilities, or even home appliances, calibration is essential for reliable and precise readings. In this document, we will delve into the importance of calibration, its various applications, and the different methods and techniques employed to achieve accurate measurements.What is Calibration?Calibration is the process of comparing measurements or readings obtained from an instrument or device with a known reference or standard. It aims to minimize measurement errors and ensure that the instrument is providing reliable and accurate results. By calibrating an instrument, we can establish its traceability to a recognized national orinternational standard, ensuring that the measurements are accepted universally.The Importance of CalibrationThe significance of calibration cannot be overstated, as it affects various aspects of our lives. Let's explore some of the key reasons why calibration is crucial:1. Accuracy and Reliability: Calibration ensures that instruments provide accurate and reliable measurements. This is particularly critical in scientific research, healthcare, manufacturing processes, and environmental monitoring.2. Compliance: Many industries are subject to regulatory standards and requirements. Calibration helps organizations comply with these standards, ensuring that they meet legal obligations and avoid penalties or legal issues.3. Quality Control: Calibration ensures that products and services meet predetermined quality standards. By calibrating measuring instruments regularly, manufacturing companies can maintain consistent quality, minimize defects, and enhance customer satisfaction.4. Safety: In sectors like healthcare, aviation, and automotive, accurate measurements are vital to ensuring safety. Calibration helps identify and rectify any inaccuracies in instruments, ensuring reliable and safe operations.Methods of CalibrationThere are various methods employed for calibration, depending on the instrument or device being calibrated. Let's explore some common calibration techniques:1. Comparative Calibration: This method involves comparing the measurements of the instrument under calibration with a reference instrument that is known to be accurate. The two instruments are subjected to the same input, and the differences in readings are adjusted to minimize errors.2. Direct or Primary Calibration: In this method, the instrument is calibrated directly against a known and traceable standard. The standard may be a physical artifact, like a weight or length, or it may be an electronic standard, such as a voltage or current.3. Interpolation Calibration: This method is employed when the instrument cannot be calibrated directly against a standard. Instead, measurements are obtained at a few specific points, and the values in between are estimated using mathematical interpolation techniques.4. Recalibration: Over time, instruments may drift or deviate from their original calibration. Recalibration involves adjusting the instrument back to its original calibration standard. Regular recalibration helps maintain accuracy and prolong the life of the instrument.Applications of CalibrationCalibration finds applications across various fields and industries. Some notable examples include:1. Laboratory Testing: Calibration is fundamental in laboratories where accurate and reliable measurements are crucial for research, experiments, and data analysis. Instruments such as balances, pipettes, spectrometers, and thermometers are regularly calibrated to ensure precise results.2. Manufacturing: Calibration is essential in manufacturing processes to maintain consistent quality, avoid defects, and comply with industry standards. Instruments used for measuring dimensions, pressures, temperatures, and electrical parameters are calibrated to ensure accuracy.3. Healthcare: In the healthcare sector, calibration is critical for medical devices such as blood pressure monitors, thermometers, infusion pumps, and diagnostic instruments. Accurate measurements are vital for patient safety and effective treatment.4. Environmental Monitoring: Instruments used for monitoring air quality, water quality, radiation levels, and weather conditions must be calibrated to provide accurate data. This ensures informed decision-making and timely actions for environmental preservation.ConclusionCalibration is a fundamental process that ensures accurate measurements and reliable results in various fields. Whether it is in laboratories, manufacturing facilities, healthcare, or environmental monitoring, the importance of calibration cannot be overstated. By adhering to calibration practicesand using appropriate techniques, we can enhance the accuracy, safety, and quality of measurements, ultimately benefiting society as a whole.。

envi的radiometric calibration工具原理 -回复

envi的radiometric calibration工具原理-回复Radiometric calibration is a crucial step in the field of remote sensing, as it ensures the accuracy and comparability of the data collected by different sensors and platforms. The radiometric calibration tool used by the ENVI software package employs a set of algorithms and mathematical transformations to convert raw image data into radiometrically calibrated imagery. In this article, we will explore the principles behind the radiometric calibration process and understand how it works in the context of ENVI.Step 1: Understanding Radiometric CalibrationRadiometric calibration involves converting the raw digital numbers (DN) recorded by the sensor into physical units of radiance or reflectance. The calibration process compensates for sensor variations, atmospheric effects, and other factors that affect the radiometric values of the captured data. It essentially establishes a quantitative relationship between the recorded DN values and the corresponding physical measurements.Step 2: Sensor Calibration ParametersTo perform radiometric calibration in ENVI, accurate knowledge of the sensor calibration parameters is essential. These parametersinclude gain, offset, saturation values, and wavelength-dependent response functions. The calibration process utilizes these parameters to transform DN values into radiometric values.The gain factor represents the conversion factor from DN to radiance units, while the offset compensates for any potential bias in the sensor's measurements. Saturation values indicate the maximum DN value that can be recorded by the sensor without saturating. Lastly, the wavelength-dependent response functions describe the sensor's sensitivity to different wavelengths.Step 3: Dark Current and Read Noise CorrectionsDark current and read noise are two common sources of noise in remote sensing data that can affect the accuracy of radiometric calibration. Dark current refers to the electrical signal generated by the sensor even in the absence of incident light. Read noise arises during the process of converting analog signals to digital values.ENVI's radiometric calibration tool applies dark current and read noise corrections to remove these sources of noise. By subtracting the dark current signal from the raw data and reducing the read noise, the tool enhances the accuracy of the radiometric calibrationprocess.Step 4: Atmospheric CorrectionsThe radiometric values collected by satellite sensors are often affected by atmospheric interference. Atmospheric gases and particles scatter and absorb solar radiation, leading to errors in the measured radiance or reflectance values. ENVI's radiometric calibration tool employs atmospheric correction techniques to account for these atmospheric effects.Atmospheric corrections utilize radiative transfer models and atmospheric parameters to estimate and remove the atmospheric interference. By estimating the atmospheric path radiance and transmittance, the tool can accurately reconstruct the true radiance or reflectance values at the sensor level.Step 5: Spectral Response Function CorrectionsDifferent sensors have varying spectral response functions, which define their sensitivity to different wavelengths. ENVI's radiometric calibration tool accounts for these spectral response function variations by applying corrections to ensure consistency among different sensors.The tool utilizes the known spectral response function of the sensor to correct the radiometric values accordingly. This correction aligns the measurements from different sensors to a common radiometric scale, facilitating comparison and analysis of imagery collected by multiple platforms.Step 6: Validation and VerificationThe radiometric calibration process is not complete without validation and verification steps. ENVI's radiometric calibration tool provides the capability to compare the calibrated data against ground-truth measurements or reference data. This step allows users to evaluate the accuracy and reliability of the radiometric calibration results.By comparing the calibrated imagery with field measurements or reference datasets, users can quantify the uncertainties associated with the radiometric calibration and assess the suitability of the calibrated data for various applications.ConclusionENVI's radiometric calibration tool plays a vital role in ensuring theaccuracy and comparability of remote sensing data. By applying a series of corrections for sensor variations, atmospheric effects, and spectral response function variations, the tool transforms raw digital numbers into radiometrically calibrated imagery. This calibrated imagery provides researchers and analysts with reliable and accurate data for a wide range of applications, including land cover mapping, agriculture monitoring, and environmental modeling.。

美国加州一名音响工程师的哲思(2)

美国加州一名音响工程师的哲思(2)

美国加州一名音响工程师的哲思(2)武夷山摘译Rick Delmonico是美国加州的一名音响工程师,自称是思想采集者。

下面是他的一些零星哲思(Philosophical Observations)。

原文来自Academia网站。

这是我编译的第二部分。

Stasis→process→chaos.静止→过程→混沌Sameness→perception→otherness.同一→感知→他者Symmetry→motion→difference.对称→运动→差异Truth→communication→randomness.真相→传播→随机这里的想法是,对称不包含运动,不包含过程,是完全静止的。

一个无维度、无尺度的点,但从信息角度说,它富含多种可能性。

科学中的高度奇异性来自不确定性。

科学这个行当就是要对事物做出解释,而这个不确定性是解释的拦路虎。

物质具有一种从信息场涌现出来的物质性。

信息具有一种从奇点涌现出来的有变异的精神性。

这一变异是创造的回响,不可能回到当初的出发地。

真理是现实的中心内核,虽说人们自以为能发现真理,但他们逐渐意识到,他们只能在一定分辨率上给真理以一瞥,超出这个分辨率,主观推理就总要上场。

真相是系统的最高能态。

真相更像一个名词,而欺骗更像一个动词。

并不是说我觉得真理是相对的,真理肯定是存在的,然而,我们与真理的唯一联系在于创造的回响。

真理具有纯粹性和对称性,像一个完美的金刚石。

不存在没有变异的现实,因此,真理从中心分岔出去,表现为概率之涨落,进入不确定性的外围暗区。

如果现实既包含无限又包含单一,那么现实就要么是多面的宝石,要么是奇点在舞蹈。

小提琴手是自参照的噪音。

光并不经历时间,只有系统才经历时间。

真理具有最大的潜势,不确定性具有最大的变异。

当我们谈论信息时,想象力具有能势的形态,包含着真相程度之涨落。

如果我们说到有意义信息的话,则应当说,简单比复杂包含了更多的潜力。

简单更接近真理。

没有什么比简单流畅的表达式更美了。

超声造影剂对生物壁面的声孔效应研究

超声造影剂对生物壁面的声孔效应研究近年来,超声介质的使用在医学影像中越来越普遍,而超声造影剂(USP)在超声诊断中也受到越来越多的关注,它被认为是改善超声成像的有效策略。

然而,对于USP对生物壁面的声孔效应的研究尚不清楚。

本文主要讨论USP对生物壁面的声孔效应。

首先,USP可以使生物壁面有效地反射超声波,并且其反射能量可以显著增加,从而提高图像质量。

这是因为USP具有高屈折率,当超声波穿过USP时,其能量会得到增强,从而使壁面更为有效地反射超声波。

此外,USP可以减少声孔现象。

声孔是超声波照射到生物壁面时发生的一种现象,它可以降低图像质量,并且可能会引起误判。

USP可以有效地抑制声孔现象,因此可以改善图像质量。

其次,不同的USP有不同的声孔效应。

USP的结构、尺寸和化学成分等因素会影响其声孔效应。

例如,某些USP的结构更加复杂,尺寸更小,可以使反射超声波的能量更大,从而减少声孔现象。

同时,USP的化学成分也会影响其反射能量,不同的化学成分可以产生不同的反射能量。

因此,USP不同的结构、尺寸和化学成分会产生不同的声孔效应。

最后,可以利用模拟实验来确定USP对生物壁面的声孔效应。

对USP与壁面的超声波的反射进行实验,可以测量USP的反射能量,评估USP反射能量与声孔之间的关系,并评估其声孔效应。

此外,也可以关注USP在不同结构、尺寸和化学成分下对声孔现象的影响,从而了解这些因素对声孔效应的影响。

综上所述,USP是超声诊断中使用比较多的一种介质,对生物壁面的声孔效应有很大的影响。

USP可以通过增强反射超声波的能量或抑制声孔现象来改善超声成像的质量。

不同的USP结构、尺寸和化学成分会产生不同的声孔效应。

最后,可以利用模拟实验来确定USP对生物壁面的声孔效应。

Calibration Analyses for Sounding Channels of MWHS Onboard FY-3ASongyan Gu,Yang Guo,Zhenzhan Wang,and Naimeng LuAbstract—The Microwave Humidity Sounder(MWHS)is a five-channel microwave radiometer in the range of150–191GHz onboard FengYun3(FY-3).Before the launch of FY-3A,the inten-sive thermal vacuum(TV AC)tests for MWHS had been carried out in a2-m TV AC chamber,and the basic parameters such as re-ceiver nonlinearity were obtained.Four-year operation shows that the performance of FY-3A MWHS remains stabile.The variations among space views and warm target views in the interval of scan lines were generally within20counts.In addition,the temperature fluctuation of the warm target in a single pass is within0.5K.Pri-marily,due to the nonlinearity correction obtained from the TV AC test,radiance measurements of MWHS agree well with NOAA-17 AMSU-B and NOAA-18Microwave Humidity Sounder(MHS) data.Averaged brightness temperature differences between FY-3 MWHS and NOAA-17AMSU-B,at simultaneous cross-overpass points,are less than1.08K for the channels at183±1GHz. In the observation-minus-background comparison,the observed and simulated brightness temperature biases of FY-3MWHS and NOAA-18MHS exhibit similar performance in the183.31±1GHz channel;but in the183.31±7GHz channel,MWHS agrees better with background.It is anticipated that FY-3MWHS data will contribute to numerical weather prediction.Index Terms—Calibration,cross comparison,FY-3A MWHS.I.I

November9,2011,respectively.FY-3’s vertical sounding package is composed of Microwave Humidity Sounder(MWHS),InfraRed Atmosphere Sounder(IRAS),and Microwave Temperature Sounder(MWTS),in which MWHS was designed for global atmospheric humidity observation in all-weather conditions and for the monitoring of severe weather systems such as typhoon and rainstorm[1].Assimilation of MWHS will improve the

Research(CSSAR)of Chinese Academy of Sciences provided twoflightmodels for FY-3,i.e.,A and B.To determine MWHS’s radio-metric characteristics,the engineering model thermal vacuum(TV AC)tests were completed before the launch of the satellite.This paperfirst introduces the MWHS instrument,particu-larly its channels’characteristics and its on-orbit calibrationprocess.The observations from FY-3MWHS are comparedwith those from NOAA-17AMSU-B equivalent channels.Fur-thermore,the observed and simulated brightness temperaturebiases of FY-3A MWHS and NOAA-18Microwave HumiditySounder(MHS)are derived and compared.II.G ENERAL D ESCRIPTION OF MWHSMWHS is a total-power microwave radiometer,which hasfive channels in the range of150–191GHz.Three soundingchannels have a center frequency at the183.31-GHz watervapor absorption line(183.31±1,183.31±3,and183.31±7GHz),each with two passbands and only sensitive to verticalpolarization at nadir.Two window channels are at150GHz,with different polarizations(e.g.,vertical and horizontal)[4].The instrument photo is shown in Fig.1,and the functionalblock diagram is shown in Fig.2[16].More details of thespectral characteristics of MWHS are described in[5].In the normal working mode for MWHS on orbit,twooffset-fed parabolic antennas are perpendicular to theflighttrack.MWHS performs cross-track scanning with a swath of2700km and a local equatorial crossing time of10:20A.M.The incident microwave radiation is fed to a corrugated feedhorn via reflectors;then,polarization is segregated for150-GHzchannels,and the beam is split by a quasi-optical system intothree required frequency bands for183GHz to obtain theobservation expressed in the form of counts.Each receiver isoperated in double-sideband mode to improve the sensitivity.The signals are amplified and integrated for12.75ms and then 0196-2892/$31.00©2012IEEET b,i=mj=1w i,j T i,jmj=1w i,j+ΔT b(2)GU et al.:CALIBRATION ANALYSES FOR SOUNDING CHANNELS OF MWHS4887 Fig.3.Basic calibration data distribution during an orbit observing.The black,red,and blue lines represent channels3,4,and5,respectively.(a)Averaged space view of channels3,4,and5.(b)Averaged internal blackbody view of channels3,4,and5.(c)Instrument temperature.(d)Averaged PRT temperature.The average calibration data of FY-3MWHS are very consistent among the three views.Thefluctuations of averaged calibration data between scan lines are generally within20counts.In addition,the warm target temperature justfluctuated at0.5K during an orbit observing.All those make a good radiance calibration of MWHS.where T b,i is for the average temperature of the internal warm target in a scan,w i,j is for the average weight coefficient.In the FY-3MWHS processing system,w i,j=1,i.e.,a constant for all the PRTs;and m is the number of PRTs after the quality control.Each of thefive PRTs is represented as T i,j.If the temperature difference of the PRT is over0.1K,the data are considered abnormal and are not used in the temperature aver-age.Because of that,m is equal or less than5.If the difference between the current scan T b,i and previous scan T b,i−1is over 0.1K,T b,i is also considered abnormal,and T b,i−1is used for the warm target mean temperature of the current scan.The correction factorΔT b for internal target temperature is based on the ground vacuum test data analysis.In the calibration procession,three samples of space views and internal warm target views are made for each channel during a scan period.After the instrument got thermal balance, three samples should be consistent in count.Each count from each channel is checked against the specific gross limits.The measurement spread is examined against a channel-specific limit between the scans.If the basic calibration data for a channel failed in the checking,then the channel will beflagged as bad data.The calibration cycle isflagged as a bad line for any channel that failed in this checking.Then,we use the supplementary calibration results,which came from the TV AC test for the bad line.The average counts for the current calibration cycle will be computed for each channel that has not beenflagged as bad. The average counts equal to an average of good data of this calibration cycle.There is one value for each channel,except for those channels that areflagged as bad.During calibration procession,the calibration cycle is with seven scans,which are also used for all the other two sounding payloads,i.e.,MWTS and IRAS.The seven scans’calibration cycle can make the basic calibration data stable enough,and that which comes from the TV AC test.In the TV AC test,the variation of noise equivalent temperature(NEΔT)with the number of scan lines included in the average of the space view and internal target view counts could almost disappear after the number up to7[7]. In order to further reduce the measurement noise,the av-eraged calibration data will be smoothed over a number of calibration cycles.This is done by computing a normalized smoothing weight function,i.e.,W j,by(3).It is a triangular weight function.The average count is calculated by(4)[8]. ThusW j=1−|j|n+1(n+1)(3)where j=−n,...,+n is the number of scan lines,which is separated with a pending calibrated scan line in a scan period. j=0is the pending calibrated scan line.The weight coefficient W j and a constant n(n=3)are also included in(3).ThusC p(i,l)=mk=1W k×C p(i,k)mk=1W k(4)where p=c or p=w is the observed counts of space(p=c: cosmic view)or blackbody(p=w:warm blackbody view), respectively;i is the channel number of MWHS from1to5; l is the scan line number;k is the number of data,which pass through the quality control of the l scan line in the calibration cycle;m is the total number of calibration observed counts,4888IEEE TRANSACTIONS ON GEOSCIENCE AND REMOTE SENSING,VOL.50,NO.12,DECEMBER2012which pass the quality inspection in the calibration cycle;and W k is the weight coefficient determined by(3). Occasionally,the moon also passes through the MWHS space view and affects the calibration if not corrected.The length for affecting the calibration is about10min per orbit for ten consecutive orbits.The moon radiation can increase to 30K,in the brightness temperature associated with MWHS space view counts,and can result in an8-K bias for the Earth view brightness temperature if not corrected.Various strategies have been developed to correct the jumps in the space view counts.The position of the moon is calculated using a standard astronomical formula,which allows for calculating the angle between the moon and the MWHS space view.Space view data will be rejected if the angle is less than0.5◦.If the space views were contaminated,the count is identified as abnormal,and then,only the samples with the lowest space view counts are used.If all three samples are contaminated by the moon,the contaminated data are all removed,and the cold count is derived from an extrapolation[17].Fig.3shows the calibration data distribution during an orbit period for the average counts of space and blackbody views, the instrument temperature,and the averaged PRT temperature. Overall,the difference of average calibration data between scan lines is less than20counts.In addition,the warm target temperature varies less than0.5K during an orbit observing. This calibration cycle and the average techniques make on-orbit MWHS calibration robust.B.Calibration ProcessionThe MWHS Earth scene counts are converted to brightness temperatures through three steps,including linear calibration, nonlinear correction,and correction of antenna spillover ef-fects.First,the linearity calibration[see(5)]is used to calculate the radiance R0(ic,ip).Then,the Earth observed brightness temperature T0(ic,ip)is obtained by inverse Planck’s law,i.e., R0(ic,ip)=a(ic)×C(ic,ip)+b(ic)(5) where R0(ic,ip)is for the microwave radiation for the Earth views,C(ic,ip)is for the original count,ic is for the chan-nel number(ic=1,...,5),and ip is for the scan position from1to98.a(ic)and b(ic)are the linearity calibration coefficients.The statistical analysis during the MWHS prelaunch test in-dicates that the nonlinearity is a function of the instrument tem-perature and the Earth scene temperatures.It can be corrected by a nonlinearity correcting function with three parameters,as shown in(7)in the Appendix;and we got T na(ic,ip).The instrument temperature(T inst)data are obtained in MWHS housekeeping data.Fig.3(c)shows the instrument temper-ature change during one MWHS orbit cycle.e2(ic,T inst), e1(ic,T inst),and e0(ic,T inst)are the nonlinearity brightness temperature bias correction coefficients at the reference tem-perature,as shown in Table III.There are some variations for the instrument temperature on orbit.In fact,the coefficients for other instrument temperatures on orbit may be determined by the interpolation according to the instrument temperature.For a conversion from the antenna temperature to the sen-sor brightness temperature,the antenna gain must be derived. However,the radiation energy from the other target can be also leaked into the system through the antenna sidelobes and result in a bias,which must be also removed during the calibration process.When the antenna scans through98positions of the Earth scene,the radiation entering through the sidelobes may come from deep space,satellite platform,or adjacent pixels of the Earth-atmosphere system.We get a linearity correction equation from the MWHS antenna test on the ground before launch to remove the antenna spillover effect.The antenna temperature T na(ic,ip)is further corrected by(6).Then,we get the brightness temperature of Earth views T b(ic,ip),i.e., T b(ic,ip)=r(ic,ip)×T na(ic,ip)+s(ic,ip)(6) where r(ic,ip)and s(ic,ip)are the MWHS antenna correction coefficients,which are provided by instrument vender through a lookup table.Fig.4shows the mosaic of MWHS183-GHz channels from MWHS L1data on November16,2010,which is generated by the MWHS preprocessing operational system.IV.A SSESSMENTS OF C ALIBRATION R ESULTSA.Cross-Comparison Between MWHS and AMSU-BFor the water vapor sounding system at microwave fre-quencies,all the sensors deployed today have the same water vapor absorption band at183GHz.When the sensors observe the same target at the same time,the observed brightness temperature difference should be the small and constant bias [10].NOAA17AMSU-B and FY-3A MWHS have the same characteristics such as center frequency,bandwidth,etc.In this paper,FY-3A MWHS calibration results are compared with NOAA17AMSU-B by using the data from July1to31, 2008.The time gap for matched data is less than30min. Within such a time interval,temperature of the Earth-atmosphere system remains stable over a homogeneous target area,if there is no strong weather system passing.The Visible and InfraRed Radiometer(VIRR),onboard FY-3A,operational cloud detection productions were included for MWHS pixel cloud screening.Then,we use a5×5analysis box for homogeneity checking;if the brightness temperature standard deviation is more than the threshold of1.0K[15],then that means that the analysis box is not homogeneous enough.Such 5×5box checking can also avoid the geolocation effect of one pixel bias,which will produce the mismatching for two sensors. After the homogeneity test,we also make scanning position checking.For the cross-track microwave radiometer,every pixel has a different scan angle.The brightness temperature will change with the pixel position.The data,only when they have almost the same position on the scan line,can be matched together without a limb effect.Then,the data will be averaged within a5×5box for two sensors.After matching the data for NOAA17AMSU-B and FY-3A MWHS in time,space,and homogeneity checking in the analy-sis area,more than2500data are derived all over the world.The brightness temperature of matched targets is cross-compared to get the relative bias of calibration results for FY3A MWHS. Statistical comparisons are performed by calculating the mean and the standard deviation of the brightness temperature dif-ference between MWHS and AMSU-B.It can be seen that the standard error tends to be a little bit larger(2.56K)for channels with weighting functions that peak lower in the atmosphereGU et al.:CALIBRATION ANALYSES FOR SOUNDING CHANNELS OF MWHS4889Fig.4.Globe image mosaic of FY-3A MWHS 183.31-GHz channels on November 16,2010.(a)183.31±1GHz.(b)183.31±3GHz.(c)183±7GHz.(channel at 183±7GHz);this is probably due to the channels were more susceptible to the time and location differences,although they are carefully controlled in the data matching method,and due to some noise for the MWHS channel at 183±7GHz.Overall,the observation brightness temperatures of MWHS and AMSU-B are very consistent,and the RMSE for channels is between 1.08and 3.07K (see Table II)parison Between the Theoretical Simulation and the Observation of BrightnessThe MWHS three channels at 183GHz have the same center frequency as channels at 183GHz of MHS.The quality of theTABLE IIC ROSS -C OMPARISON R ESULTS AT S IMULTANEOUSC ROSS O VERPASSES (SCO)POINTS4890IEEE TRANSACTIONS ON GEOSCIENCE AND REMOTE SENSING,VOL.50,NO.12,DECEMBER2012GU et al.:CALIBRATION ANALYSES FOR SOUNDING CHANNELS OF MWHS4891where e2(ic,T inst),e1(ic,T inst),and e0(ic,T inst)are the re-gression coefficients shown in Table III for the nonlinearity correction equation corresponding to the instrument temper-ature T inst and channel ic;ΔT(ic)is the nonlinearity bias correction amount;T0(ic)is the Earth target temperature, which is obtained by R,which is a linear calibration result and reconverted into temperature by Planck’s law;and T na(ic) is the corrected antenna nonlinearity temperature.Through a nonlinearity correction,the maximum temperature deviation of three sounding channels is not more than0.37K,as shown in Table III.The nonlinearity correction of a quadratic equation with three parameters has been used in the FY-3A MWHS operational preprocessing system.A CKNOWLEDGMENTThe authors would like to thank Dr.J.Li and Dr.S.Zhang of CSSAR for providing the MWHS TV AC test data.They would also like to thank the reviewers and editors for all valuable suggestions that helped improve this paper.R EFERENCES[1]C.Dong,J.Yang,Z.Yang,N.Lu,J.Shi,P.Zhang,Y.Liu,B.Cai,andW.Zhang,“An overview of a new Chinese weather satellite FY-3A,”Bull.Amer.Meteorol.Soc.,vol.90,no.10,pp.1531–1544,Oct.2009.[2]L.Guan,X.Zou,F.Weng,and G.Li,“Assessments of FY-3A MicrowaveHumidity Sounder(MWHS)measurements using NOAA-18Microwave Humidity Sounder(MHS),”J.Geophys.Res.,vol.116,no.10,p.D10106, May2011.[3]Q.F.Lu,“Initial evaluation and assimilation of FY-3A atmosphericsounding data in the ECMWF system,”Sci.Chin.Earth Sci.,vol.54, no.10,pp.1453–1457,Oct.2011.[4]J.Li,S.W.Zhang,J.S.Jiang,and X.L.Dong,“In-orbit performanceof Microwave Humidity Sounder(MWHS)of the Chinese FY-3meteoro-logical satellite,”in Proc.IEEE IGARSS,Honolulu,HI,Jul.25–30,2010, pp.574–577.[5]Z.Z.Wang,J.Li,S.W.Zhang,and Y.Li,“Prelaunch calibrationof Microwave Humidity Sounder on China’s FY-3A meteorological satellite,”IEEE Geosci.Remote Sens.Lett.,vol.8,no.1,pp.29–33, Jan.2011.[6]S.Y.Gu,Z.Z.Wang,J.Li,and S.W.Zhang,“The radiometric char-acteristics of sounding channels for FY-3A/MWHS,”J.Appl.Meteorol., vol.21,no.3,pp.335–342,2010,(in Chinese).[7]W.Saunders and T.J.Hewison,“The radiometric characterization ofAMSU-B,”IEEE Trans.Microw.Theory Tech.,vol.43,no.4,pp.760–771,Apr.1995.[8]“AIRS project algorithm theoretical basis document—Part3:Microwaveinstruments,”California Inst.Technol.,Pasadena,CA,JPL D-17005, Version2.1,2000.[9]R.W.Raunders,“Results of AMSU-B radiometric characterization tests,”Met O(RSI)Branch Memorandum No.18,1995.[10]NOAA KLM User’s Guide(Satellite and data description of NOAA’s Polarorbiting satellites from NOAA-15and later),NOAA NCDC,Asheville, NC,Feb.2009.[11]T.Mo,“Calibration of the advanced microwave sounding unit-A radiome-ters for NOAA-N and NOAA-N,”NOAA,NESDIS,Washington,DC, NOAA Tech.Rep.NESDIS106,2002.[12]T.Mo,“Calibration of the advanced microwave sounding unit-A forNOAA-K,”NOAA,NESDIS,Washington,DC,NOAA Tech.Rep.NESDIS85,1995.[13]T.Mo,“NOAA-L and NOAA-M AMSU-A antenna pattern corrections,”NOAA,NESDIS,Washington,DC,NOAA Tech.Rep.NESDIS98,2000.[14]brot,vanant,and K.Whyte,AAPP Documentation ScientificDescription(AAPP-1).Darmstadt,Germany:EUMETSAT,2002.
