FIELD: hydroacoustics, applicable for identification of objects according to their noise radiation.
SUBSTANCE: the method includes reception of the signal of noise radiation of the noisy object by the first receiving antenna and spectral analysis of the received signal of noise radiation of the noisy object, reception of the signal of noise radiation is also performed by the second receiving antenna, separated is the reciprocal spectrum of the signals of noise radiation received by the first and second receiving antennas, measured is the value of the carrier frequency of the autocorrelation function, and the decision on the class of the noisy object is taken at comparison of the measured carrier frequency of the autocorrelation function with threshold frequencies, each being determined as an average frequency of the initial noise radiation band of each standard object of a definite class.
EFFECT: enhanced efficiency of classification of noisy objects according to the spectral characteristics of their noise radiation.
