Abstract: FIELD: acoustic instruments for seismic prospecting. SUBSTANCE: device has channels 1 and 2 for detection of sound pressure and oscillation rate. Said channels are connected to input of multiplier 3. Single half-period direct-polarity peak detector 4 is connected to output of multiplier 3. Detector 4 is connected to recording unit 5. Device provides possibility to suppress secondary signal caused by reflection from water surface due to opposite polarity of these signals. Level hydrodynamic noise is decreased due to relative- correlation processing of signals from channels 1 and 2 in multiplier 3. In addition single half-period inverse-polarity peak detector 6 is introduced in order to use secondary signal caused by reflection from water surface. Detector 6 detects secondary signal and sends it to input of adder 9 through inverter 7. Line 8 provides time delay that is equal to ratio of double depth of tugged antenna to speed of sound in water. Output of delay line 8 is connected to input of adder 9. This results in in-phase addition of direct and secondary signals. This results in possibility to nearly double signal-to-noise ratio without change in level of noise. In addition signals from channels 1 and 2 for detection of sound pressure and oscillation rate are sent to identical units of band-pass filters 10. This results in possibility of spectral analysis of wide-band probing signals. Secondary signals caused by reflection from water surface are clipped by direct-polarity peak detectors. EFFECT: increased signal-to-noise ratio, increased precision. 3 cl, 5 dwg
