RECEIVING PATH OF MULTICHANNEL HYDROACOUSTIC COMPLEX Russian patent published in 2021 - IPC G01S7/52 

FIELD: hydroacoustics.

SUBSTANCE: invention relates to the field of hydroacoustics and can be used to build long-running coherent multichannel receiving paths of hydroacoustic complexes. To achieve the technical result, the receiving path of a multi-channel hydroacoustic complex contains a source of a stimulating signal that enters the inputs of the frequency response and frequency response non-identity compensation unit of amplitude-frequency response and circuit-phase response in the control mode through acoustic receivers and then into the data compaction and transmission system, which is connected to the spatio-temporal processing unit. Automatic compensation for the non-identity of the signal channels is performed using the reference channel. In the non-identity compensation block in the monitoring mode, the signals of the working channels are compared with the reference one, and the correction coefficients are calculated and stored, which are used in the operating mode to compensate for the non-identity of the working channels.

EFFECT: automating the process of compensation for the non-identity of the amplitude-phase characteristics of the receiving paths of a multi-channel hydroacoustic complex.
