Interferogram formation in the holographic processing of sonar noise signals

<jats:p>The principles of constructing interferogram schemes in the holographic processing of noise sonar signals are described. The influence of these interferograms on the noise immunity of processing is considered. It is shown that the most promising interferogram scheme is composed of noise realizations received at various time points. An experimental method is proposed to estimate the correlation coefficient of temporal fluctuations of background noise.</jats:p>
