FIELD: hydro-acoustics, possible usage for limiting masking effect of noises, developed by carrying watercraft, in particular, noises of hydro-dynamical origin on receiving elements of hydro-acoustic antenna.
SUBSTANCE: method for selecting acoustic signal on background of interference field is based on correlation of noise emission of watercraft, received via pressure channel with following averaging of output signal by time.
EFFECT: increased ratio signal/interference, which due to simultaneous receipt of signal and interference via pressures channel and oscillating speeds channel.
