FIELD: physics.
SUBSTANCE: device for processing and detection of hydroacoustic signals comprising narrow-band filter comb, detectors, integrators, commutator and threshold detector, is equipped with multi-channel circuit for maximum signal separation, inlets of which are connected to outlets of integrators, outlet - to signal inlet of threshold detector, and reference inlet of threshold detector is connected to commutator outlet.
EFFECT: increased efficiency of narrow-band signals detection on background of noise interference, which is non-stationary in spectrum.
