FIELD: acoustics.
SUBSTANCE: invention relates to hydroacoustic and can be used in tasks for object class determination during hydroacoustic systems development. Result is achieved by that, in disclosed method when detecting and classifying marine object provides eliminating effect of carrier ship intrinsic noise spectrum, directly acting on hydroacoustic devices antenna arranged on object, and thus ensuring correct classification spectral criteria determination.
EFFECT: technical result consists in provision of reliable determination of noise emission signals spectral classification features.
