FIELD: hydroacoustics.
SUBSTANCE: invention serves to solve the problems of signal processing in passive sonars, and is intended to determine the set of coordinates of a noise-generating object. The method is based on receiving a hydroacoustic noise signal of an object by a set of several antennas located in a horizontal plane, when the wave front can be taken as spherical, the analysis of the cross-correlation functions of the received signal makes it possible to determine the distance to the object, when implementing the method, the analysis of the autocorrelation function of the signal received at the one main antenna, based on comparison with the time parameters of the predictive calculation of the beam structure of the signal in the vertical plane, is carried out, and additional procedures allow to determine the depth of the object.
EFFECT: unambiguous determination of the immersion depth of an object by a uniquely defined distance to it when they are visually observed on the indicator screen.
