METHOD FOR CONTINUOUS MONITORING OF THE RECEIVING PATH OF THE SHIP'S HYDROACOUSTIC COMPLEX Russian patent published in 2022 - IPC H04R29/00 

FIELD: hydroacoustics.

SUBSTANCE: invention relates to the field of hydroacoustics and measuring technology, and can be used to determine the technical condition of the receiving path of the ship’s hydroacoustic complex. Essence: in the method for continuous monitoring of the receiving path of the ship’s hydroacoustic complex, the input of each channel of the noise acoustic signal receiving path is affected, the RMS value of the noise signal parameters at the output of each channel is determined, the obtained parameter values are compared with the maximum permissible value, the formation of an array of channel states and the determination of channels corresponding to the norm in which analog-to-digital conversion and spectral processing of signals at the output of channels corresponding to the norm are carried out, the level of voltage change at the output of each of these channels is analyzed before the analog-to-digital conversion for a time Δt equal to the control period, and if there is no voltage change in any channel after the analog-to-digital conversion, this channel is considered to have failed, and this procedure is repeated throughout the entire operation time of the receiving path of the hydroacoustic complex.

EFFECT: increased reliability and informativeness of continuous monitoring.
