This paper investigates effectiveness of sea reverberation suppression by adaptive array processing. The case of monostatic active sonar is considered. The models of multipath echo signal, reverberation and sea surface noise are presented. The model of the array steering vector averaged on medium fluctuations is used for robust adaptive beamforming in a random oceanic waveguide. Computer simulations for typical shallow water conditions are given.
