An adaptive noise-resistant algorithm for holographic processing of hydroacoustic signals is presented, which provides restoration of the distance and radial velocity of underwater noise sources in shallow waters in the absence of information about the characteristics of the propagation medium. The algorithm is based on the measured values of the source hologram. The results of numerical simulation are presented. An analysis of the stability of the algorithm for estimating the source parameters with respect to intense internal waves that determine the horizontal refraction of sound field modes is performed.
