FIELD: hydroacoustic engineering.
SUBSTANCE: invention is related to the field of hydroacoustic engineering and may be used in design and modernisation of hydroacoustic stations. Device comprises system for compensation of Doppler frequency shift cause by movement of sonar carrier vessel, device for formation of receiving characteristic of directionality, amplifier with amplification correction by reverberation and amplifier with frequency converter, to outlet of which noise channel is connected with amplifier-limiter or controlled amplifier and comb of filters and reverberation channel with comb of filters and controlled amplifiers. To achieve technical result, amplifier with amplification control by reverberation is included into reverberation channel between outlet of frequency converter and inlet of filters comb.
EFFECT: higher efficiency of echo signals detection outside reverberation spectrum.
