The paper "Improving the Noise Immunity of the Combined Hydroacoustic Receiver KGP10" has been published in Instruments and Experimental Techniques Journal (in Russian)

The author is the Senior Researcher of the Laboratory of Acoustic Investigation of IKIR FEB RAS, Cand. Sci. (Phys.-Math.) Shcherbina Albert Olegovich.

The paper considers practical methods for improving the noise immunity of combine hydroacoustic receivers of co-oscillating type KGP10 produced by VNIIFTRI. Measures for improving the shielding of the measuring channel are presented. The possibility of change of the complex preliminary amplifier, constructed according to charge amplifier, by a high-impedance voltage amplifier was considered. As the result of the work, it was succeeded to eliminate all kinds of electric noises and to increase the signal/noise ratio from 15 to 36 dB.
