FIELD: hydroacoustics.
SUBSTANCE: invention is intended for detecting a noisy marine object using a discrete extended antenna. Essence: the curvature of the wave front in the method is taken into account by the totality of delays in signal reception to individual antenna elements, while the delays are formed as arguments for the maximum cross-correlation functions of the signal between individual antenna elements. This allows you to increase the resulting power of the received signal, and therefore improve the efficiency of detecting a noisy object in the sea.
EFFECT: operational measurement and accounting of the curvature of the wave front arriving at the antenna aperture for in-phase addition of signals from individual elements.
