美军雷达命名规则和雷达英文词汇e
美军雷达命名标准按老美军用标准MIL-STD-196D规定，其军用电子设备〔包括雷达〕根据联合电子类型命名系统〔JETDS〕。
名称由字母AN〔陆军-海军联合命名系统〕,一条斜线和另外三个字母组成。
三个字母表示设备安装位置，设备类型和设备用途。
比方AN/SPS-49表示舰载警戒雷达。
数字49标识特定装备，并且表示该设备时JETDS规定的SPS类的第49种。
经过一次修改就在原型后附加一个字母如ABC，名称后加破折号，T和数字表示丫是用来训练的。
名称后的括号内V表示丫是可变系统，就是通过增加或减少设备来完成不同功能的系统。
处于试验和研制中的系统有时在紧随正式名称后的括弧内用特殊标志来表示，他们用来指明研究单位。
比方XB表示海军研究实验室，XW表示罗姆航空开展中心。
下面就把AN/***后面的三个字母的意思祥加说明。

互耦效应在天线阵列设计中的研究与应用
摘要摘要随着社会的发展和科学技术的进步，现代通信技术得到了飞速地发展，在军用和民用中所产生的数据越来越大。
不管是在即将到来的5G时代还是方兴未艾的物联网中每时每刻都进行着大量的信息交换，并且通信数据量呈现出爆炸式增长的趋势。
天线在通信系统中充当信息的发送和接收的角色，其重要性不言而喻。
根据香农定理，带宽越宽可传输的信息量也就越大，所以超宽带天线也就应运而生；从美观、安装方便和易于共形的角度，天线需要满足低剖面的要求。
在通信系统中使用多天线不仅可以减小瑞利衰落的影响还可以增大通信系统的数据量，但是一般的相控阵天线，都会受到地板和天线单元之间互耦的影响而降低通信系统的性能。
近年来出现一种新型超宽带天线：紧耦合天线阵列。
它具有超宽带、易于安装、低剖面的特点，可以有效地解决上述问题。
本文基于紧耦合天线阵列设计思想，对阵列天线的互耦效应进行了研究与利用。
论文的主要工作包括以下几个部分：1、分析了平面紧耦合天线的原理。
首先分析了地板对平面天线阻抗和带宽的影响。
然后研究了紧耦合天线阵列的等效电路和阻抗，讨论了带有地板平面天线在天线上层和下层添加不同材料的介质层可实现的极限带宽。
2、设计了一种紧耦合超宽带交织螺旋天线，天线的带宽为5GHz-30GHz(6:1)，并对其在不同频率时的方向图进行了研究与分析。
采用主从边界的方法在对天线优化后，⨯的阵列，该天线阵列具有良好的增益带宽和轴比带宽。
对常用的设计仿真了一个33平衡馈电巴伦进行了分析，设计了一款共面波导到平衡微带线转换的馈电巴伦，带宽1GHz-9.5GHz，该巴伦具有结构简单便于加工，易与天线集成等优点。
3、研究了紧耦合偶极子天线阵列。
首先采取无限周期性结构的方式对天线单元进行了仿真优化，分析了天线的电路等效，分别从场和路的两种思想对耦合效应对天线带宽的影响进行了讨论。
然后分析了有限单元天线阵列的边缘截断效应，并采用延⨯天线阵列长边缘单元天线臂的方式有效的减小了边缘截断效应。

Abstract
Antenna array as high-gain antenna has been widely used in various communication systems. However, the characteristics of antenna array changed fundamentally due to the mutual coupling between elements. That coupling is not negligible especially when the element spacing is small. Because of the effect of coupling, the distribution of array aperture, the input impedance and the radiation pattern were changed. It is necessary to analyze the mutual coupling in antenna array deeply and make some compensation, particularly in the development of high-performance antenna array such as low side-lobe antenna and ultra-low side-lobe antenna. That’s the reason why the analysis of the mutual coupling in antenna array has great significance and practical value. In this paper we use dipole array as an example to analyze mutual coupling in it and make certain compensation, with the purpose to illustrate the mutual coupling in slot antennas on waveguides based on the equivalence between dipole and slot antenna in their radiation pattern. Here we calculated the current distribution of a half-wave dipole antenna through the Matlab programming using the method of moments (MOM), and compared to the same result from the calculation of the simulation software FEKO which based on MOM to verify the correctness of the program, and then give the current distribution on each element in the linear dipole array with uniform element spacing by FEKO simulation, in this way to indicate the mutual coupling in antenna array. As the focus of this article, we analyze the mutual coupling in the dipole array which contains 104 elements and make certain of its mutual coupling compensation. By this way we illustrate the mutual coupling in a kind of irregular slot antennas on waveguides. Firstly we analyze the mutual coupling in the linear dipole array, and make certain of its mutual coupling compensation by adjusting the amplitude and phase of each element. Elements’ amplitude was weighted using Taylor incentive-weighted and their phase was adjusted by changing the length of each element according to the observation of each element’s resistance status after the simulation, so that they can achieve the minimum Voltage Standing Wave Ratio (VSWR). In this way the mutual coupling in the dipole array should compensated and its radiation performance improved; secondly we get to the analysis of the rectangular

The first tap is Ricean distributed (with K-factor K1). Other taps are Rayleigh distributed. For any considered range, the size of the ellipses and the numbers of scatterers on each ellipse are inferred from the SISO parameters corresponding to the reference range. On the BS side, a disc of exclusion is defined to take into account the impact of BS height. Similarly, a ring of local scatterers is placed around the MS to account for local scattering effects. The local scattering ratio (LSR) is defined as the ratio between the amount of local scatterers surrounding the MS to the total amount of scatterers surrounding the MS and situated along the axis between the MS and the BS. So-called rich and poor scattering environments at the MS are respectively characterized by a LSR of 1 (all scatterers with relative delay ~ 0 are located on the ring) and 0 (all scatterers with relative delay ~ 0 are located along the link axis).

综合孔径辐射计成像技术利用稀疏的小天线阵列合成大的虚拟口径[2]，对目标场景进行成像及探测具有波束控制灵活[3]、信号增益高、抗干扰能力强及空间超分辨率能力高等优点，因而受到极大的关注[4]。
但在实际应用中，阵元间的互耦[5]、阵元幅相误差[6,7](包括各阵元性能不一致和通道间的幅频和相频特性不一致)、阵元位置误差等[8]，会降低毫米波辐射计的探测性能与成像效果。
本文主要研究阵元幅相、位置误差的校正方法。
目前，国内外一些学者正致力于阵列误差校正方法的研究，现有的校正方法主要分为盲校正[9,10]和有源校正两大类[11,12]。
有源校正是在空间设置方位已知的辅助源对阵列误差参数进行离线估计，这类算法运算量小、实现简单，在实际中应用较为广泛。

在竞争激烈的工业自动化生产过程中，机器视觉对产品质量的把关起着举足 轻重的作用，机器视觉在缺陷检测技术方面的应用也逐渐普遍起来。与常规的检 测技术相比，自动化的视觉检测系统更加经济、快捷、高效与 安全。纹理物体在 工业生产中广泛存在，像用于半导体装配和封装底板和发光二极管，现代 化电子 系统中的印制电路板，以及纺织行业中的布匹和织物等都可认为是含有纹理特征 的物体。本论文主要致力于纹理物体的缺陷检测技术研究，为纹理物体的自动化 检测提供高效而可靠的检测算法。 纹理是描述图像内容的重要特征，纹理分析也已经被成功的应用与纹理分割 和纹理分类当中。本研究提出了一种基于纹理分析技术和参考比较方式的缺陷检 测算法。这种算法能容忍物体变形引起的图像配准误差，对纹理的影响也具有鲁 棒性。本算法旨在为检测出的缺陷区域提供丰富而重要的物理意义，如缺陷区域 的大小、形状、亮度对比度及空间分布等。同时，在参考图像可行的情况下，本 算法可用于同质纹理物体和非同质纹理物体的检测，对非纹理物体 的检测也可取 得不错的效果。 在整个检测过程中，我们采用了可调控金字塔的纹理分析和重构技术。与传 统的小波纹理分析技术不同，我们在小波域中加入处理物体变形和纹理影响的容 忍度控制算法，来实现容忍物体变形和对纹理影响鲁棒的目的。最后可调控金字 塔的重构保证了缺陷区域物理意义恢复的准确性。实验阶段，我们检测了一系列 具有实际应用价值的图像。实验结果表明 本文提出的纹理物体缺陷检测算法具有 高效性和易于实现性。 关键字: 缺陷检测；纹理；物体变形；可调控金字塔；重构

我们考察在 BILUM 的构造中用稀疏近似逆技术求大块的逆。对最终的约化系统也构造 一个稀疏近似逆并用作对最终层上近似解的一个解法器。事实上，几乎所有基于 Schur 补技 术的多层方法都使用了某种稀疏近似逆技术， 其中一些是非常简单的。 对求解某些特殊结构 矩阵的某些多层方法， 尽管基于高阶多项式的一些稀疏近似逆是最优的， 但它们的实际使用 和有效实现成问题。因此，为了有效性特别是在并行计算机上，它们通常被次最优的稀疏近 似逆所代替。另外，稀疏近似逆也已与多重网格方法结合使用[1, 15, 28]，然而，在一般 目的的多层方法中使用一般目的的稀疏近似逆技术似乎是新的且有希望的。 本文的组织如下： 第 2 节给出几种一般矩阵的稀疏近似逆技术以及我们数值实现中将采 用的 AINV。第 3 节描述多层块 ILU 预条件技术。第 4 节考察在 BILUM 中使用稀疏近似逆的 好处。第 5 节给出数值例子。第 6 节是结论。

A quarter-wave transmission line section (34) is coupled between the inputs to provide such impedance, which has a value selected to offset the effect of mutual coupling on Q. For a pair of monopoles (10 and 12), the inter-element coupling line (34) is connected to the respective monopoles by quarter-wave sections (14 and 16) having impedances selected in order to provide desired input impedances. The performance of dual-element end-fire slot (Fig. 2) or dipole array antennas may similarly be improved. Linear array antennas of four or more elements (Fig.8) are provided by forced feeding of the additional elements from the basic dual-element configuration in accordance with the invention.申请人：HAZELTINE CORP地址：US国籍：US代理机构：Heusler, Wolfgang, Dipl.-Ing.更多信息请下载全文后查看。
一种矿用高隔离度三频MIMO_天线设计
一种矿用高隔离度三频MIMO 天线设计董佩佩， 徐艳红， 王安义， 张志文， 白婷婷（西安科技大学 通信与信息工程学院，陕西 西安 710054）摘要：多频多输入多输出（MIMO ）天线由于空间受限，存在单元间距较小产生的强耦合问题。
针对该问题，设计了一种矿用高隔离度三频MIMO 天线。
通过在1个矩形枝节两端加载2个L 型枝节组成三叉戟单极子天线，使天线具有三频特性；将2个三叉戟单极子天线单元对称放置，在2个单元之间的金属地板上加载1个T 型枝节，利用寄生枝节产生的相反电流抵消未加枝节时耦合产生的电流，并蚀刻2个对称的矩形槽，通过改变地板上的电流分布来抑制地板表面波带来的互耦，从而使天线在整个频段内实现高隔离度。
仿真结果表明：该天线工作在1.85～2.70，3.24～3.99，4.65～5.80 GHz 频段，能有效覆盖煤矿井下WiMAX/WiFi/4G/5G NR 工作频段；天线在3个频段内的隔离度分别大于20，22，22 dB ，较去耦合前天线的隔离度分别提高了11，9，10 dB ；包络相关系数小于0.2，具有良好的分集性能；天线在工作频段内增益变化稳定，且全向辐射特性良好。
该天线具有结构简单紧凑、易加工、剖面低的优势，在煤矿无线通信中具有广泛的应用场景。

In order to solve the above problems, a mine high isolation tri-band MIMO antenna has been designed. By loading two L-shaped branches at both ends of a rectangular branch to form a trident monopole antenna, the antenna has tri-band features. Two trident monopole antenna units are placed symmetrically. A T-shaped branch is loaded on the metal floor between the two units.The opposite current generated by parasitic branches is used to offset the coupling current without branches. Two symmetrical rectangular slots are etched to suppress the mutual coupling caused by surface waves on the floor by changing the current distribution on the floor. The high isolation of the antenna throughout the entire band is achieved. The simulation results show that the antenna operates in frequency bands of 1.85-2.70, 3.24-3.99, 4.65-5.80 GHz, can effectively covering coal mines' underground WiMAX/WiFi/4G/5G NR operating band. The isolation of the antenna in three bands is greater than 20, 22, 22 dB, respectively. It is 11, 9, 10 dB higher than the isolation of the antenna before decoupling; The envelope correlation coefficient is less than 0.2, indicating good diversity performance. The antenna has stable gain variation within the operating band and good omnidirectional radiation features. This antenna has the advantages of simple and compact structure, easy processing, and low profile. It has a wide range of application scenarios in wireless communication in coal mines.收稿日期：2022-09-29；修回日期：2023-05-18；责任编辑：盛男。

有源相控阵天线的近场校准
有源相控阵天线的近场校准焦禹;陈文俊【摘要】In order to calibrate the phased array antenna and reduce the impact of element failure and am-plitude-phase errors,this paper proposes a calibration method which considers the mutual coupling. On the basis of the calibration with the near-field scanning method,the elements is calibrated by the rotating ele-ment electric-field vector( REV) method.With the REV method,the large-scale phased array antenna is distributed into some small areas such as middle areas and edge areas to make the signal vary more signifi-cantly . The re-calibration method can find out the failure elements and improve the phased array antenna's amplitude-phase consistency. The calibration of sub-region with the REV method can diminish the effect of the mutual coupling and shorten the calibration period. The simulations validate that the method has a good accuracy to calibrate the large-scale phased array antenna and can improve the calibration results.%为实现对相控阵天线的校准，降低幅相误差和阵元失效对天线性能的影响，提出了一种考虑互耦效应的近场校准方法。

Experimental resrdts: Several FP cavities have been designed ( 3 0 0 m m < R 0 < 2 5 9 5 m m , $,=20and30mm)andcoupledtovarious feed homs (cI, L,J=((6, 9.6), (9, 16.7) m m ) . We pre!.ent here the typical performance obtained with one of these config.urations. The resonator is in fused quartz (4, = 20 mm, D = 1.260 mm) and the highly reflecting mirrors have been fabricated using a preci!;e lift-off process of sputtered chromium and copper thin films (0= 1300 pm, d = 6 5 0 p m : a,=600pm V i , 23.lo%<dJa,<55.9%, R , , = 7 0 0 m m , arg[r,] = 157"). The gold-plated brass feed hom (ch = 6 mm, Lh = 9.6 mm) is electroformed to give precise dimensions and reproducible characteristics. The gain, measurcd by the comparison method is maximum (14.5 dB) at 57.38 GHz and the efficiency 16.3 dB). Fig. 4 shows the far-field radiation equals 66% ( D o = panem in H-plane. The radiated beam is Gaussian with sidelobe and crowpolarisation levels lower than -35 and -27 dB, rcspectively. Similar patterns are obtained in E-plane. In the paraxi,al region, thc measured CO-polar component is in good agreement with theory [IO]. Finally, comparison with the pattern of the hom alone clcarly demonstrates the focusing effect produced by the FP cavity, as already observed with GBAs [ 5 ] .

Inrroducrion: Interest in the use of a multi-element antenna (MEA) at
Conclusion: A new concept of beam shaping technique has been presented and successfully validated in the 60 GHr band. The focusing device is a half-wavelength plane-parallel FP cavity :he semitransparent mirrors ofwhich are made of inductive metal meshes for a use in linear or circular polarisation. The output mirror is a nanuniform strip grating designed to behave as a spherical cquiphase surface. The resulting radiation pattems have very low sidelobes. The directivity of the antenna is adjusted by the value of the synthesised radius of cu~yaturc,i.e. the dimensions of the non-periodic: grating. This technique also enables elliptical Gaussian beams to be obtained by imposing different radii of curvatu~ein both principal planes, contrary to GBAs with plano-convex FP resonators that only radiate rotationally symmetric beams.

both the transmitter and receiver of a communications link, a so-called multiple-input multiple-output (MIMO) architecture, was sparked by the theoretical results o f Foschini and Gans [I]. It was shown that an architecture comprising n r transmit antennas and nR receive antennas provides a :system capacity proportional to n=min(n, n R ) with no cxpansion in bandwidth resources and transmit power, providing the channel is zsufficicntly rich in multipath scanering so as to exhibit independent spatial Fading between each transmit and receive element of the antennas. It is recognised that the actual instantaneous channel capacity is dependent both upon the signal-to-noisc ratio (SNR) available at the receivers and the correlations within the channel [ 2 ] . The effects that antenna array imperfections have on channel capaciry, in particular that of mutual coupling between array elements, is still an area for rescarch. Initial investigations in [3, 41 made use of modified stochastic niodcls using measured elemcnt pattems.
