FIELD: underwater irradiators. SUBSTANCE: required level of radiation is sustained by means of hydroacoustic converter connected with electric oscillation generator through power amplifier. Device also has system for auto-tuning of level of sonic pressure which has hydrophone, amplification unit and detector. Set of frequency filters, group of amplifiers with regulated amplification gain and adder are brought into the device additionally. The generator itself is multichannel. Auto-tuning system also has set of frequency filters and amplifiers. Control input of amplifiers are connected with outputs of special unit for controlling spectrum of acoustic oscillations to be radiated. Detectors are made in form of correlators provided with delay lines tunes for time of propagation of sonic oscillations from converter to hydrophone. EFFECT: improved efficiency. 5 cl, 1 dwg
