FIELD: hydroacoustic engineering.
SUBSTANCE: device comprises emitting channel, receiving channel, and additional channel for adjusting emitting signal. The emitting channel is made of generator of electric signals, power amplifier, and emitter connected in series. The receiving channel is made of the receiving hydroacoustic aerial connected with the input of the first spectrum analyzer and recorder. The additional channel for adjusting emitting signal is made of a hydrophone connected with the input of the spectrum analyzer. The receiving channel has switch, multiplier, divider, and first and second permanent memories connected in series. The output of the second permanent memory is connected with the second input of the divider, and input of the second permanent memory is connected with the output of the first spectrum analyzer through the switch. The output of the multiplier is connected with the input of the recorder. The channel for adjusting the emitting signal is additionally provided with third permanent memory and comparator that are connected in series. The output of the comparator is connected with the second input of the power amplifier. The second input of the comparator is connected with the output of the second spectrum analyzer.
EFFECT: enhanced accuracy of measurements.
