Abstract:

     The method that makes it possible to recognize sonar signals from fish accumulations against the background of bottom reflections and thus increase the detection range of fish has been developed. Examples of results of processing of actual experimental data are presented.

Keywords: hydroacoustic signal, sonar, echo signal, intercycle correlation processing, reverberation interference.
