摘要:The invention concerns methods for detecting mobile objects using an active sonar operating by Doppler effect, which consists in using as transmission signal a burst of N coded pulses so as to present a spectrum with a comb structure of lines, thereby increasing the 'signal/reverberation' ratio of the useful signal intensity over the reverberated intensity, hence the sonar efficacy. The invention enables to detect more easily mobile objects in reverberating transmission medium.
