FIELD: physics.
SUBSTANCE: in suggested route of hydroacoustic signals radiation, comprising electric generator with devices for generation, amplification and modulation of signal and hydroacoustic antenna with electroacoustic transducers, and also elements of radiation parameters control system comprising phase-sensitive detector installed in front of antenna, and one outlet of this detector is connected parallel to antenna, the other inlet - serially to it, outlet of detector by means of negative feedback is connected to modulator of generator electric power.
EFFECT: provision of cavitation-free mode of hydroacoustic signals radiation route or reduction of cavitation intensity down to certain permissible level and increased reliability and technical efficiency of route.
