METHOD FOR OPERATING CONTROL OF RECEIVING PATH OF HYDROACOUSTIC SHIP SYSTEM Russian patent published in 2020 - IPC H04R29/00 

FIELD: acoustics.

SUBSTANCE: invention relates to the field of hydroacoustics. Method of on-line control of multichannel receiving path of hydroacoustic ship complex, at which to input of each channel from channels corresponding to norm, in real time, without interrupting standard channel operation, applying stimulating electric signal U_in in operating frequency range on upper v > v_u or lower boundary of pass band v_l > v, subjecting the FFT processing to frequency-domain sections which contain a stimulus signal, calculating, using the known transmission coefficient K_tr(v) of the multichannel receiving path, the value of the expected signal at the output of each channel U_out = K_tr(v)U_in, comparing the obtained value with the specified value U_add, and those channels, in which the difference |U_add−U_out| these values exceeds allowable, consider as failed, and remaining channels are continued to undergo control procedure by stimulating signal, monitoring change in channel transmission coefficients.

EFFECT: technical result is increase in the operational control reliability and information value.
