FIELD: physics.
SUBSTANCE: method and the device for calibration of the parametric tract of the sonar that reduces the amplitude-frequency distortions of the matched filter response to the useful echo by optimizing the parameters emitted in aqueous medium of the pumping signals: the carrier frequency of the tone pumping signal, the carrier frequency and the frequency deviation of the frequency modulated pumping signal. The device for calibration of the parametric tract of the sonar contains a reference reflecting object, a high-frequency transmitter antenna and a low-frequency receiving antenna, a transmitting unit, a receiving unit, a digital signal processing unit, a control unit.
EFFECT: optimization of the pumping signal parameters emitted to the aqueous medium to ensure minimum amplitude-frequency distortion.
