METHOD OF PROCESSING INFORMATION IN HYDROACOUSTIC ANTENNA Russian patent published in 2019 - IPC G01S15/00 

FIELD: hydro acoustics.

SUBSTANCE: invention relates to the field of underwater acoustics and can be applied in the development and operation of hydroacoustic antennas for various purposes for correcting the output signals of hydroacoustic receivers. Technical problem to be solved – the improvement of the method of processing information in a hydroacoustic antenna. Technical result is achieved due to the exclusion from the obtained results of the component of the error due to the different rate of change of the parameters of the hydroacoustic receivers and accelerometers of the antenna in time. In addition, the range of use of hydroacoustic antenna sensors is enhanced by the creation of hydroacoustic waves in antiphase with the hydroacoustic wave from carrier vibration by sensors. As a result, the intensity of the total wave decreases. Likelihood of detecting a carrier by another carrier is reduced. Problem is solved by the fact that in a known method of processing information in a hydroacoustic antenna, in each of the “n” antenna cells located on the carrier body, a hydroacoustic receiver and an accelerometer measuring the parameters of the carrier body vibration are installed, the output signal of the accelerometer is subtracted from the output signal of the sonar receiver, according to the invention in each cell of the antenna there are three identical piezoelectric sensors, the first piezoelectric sensor is installed in the aquatic environment and used as a sonar receiver, the second piezoelectric sensor is isolated from the aquatic environment and used as an accelerometer, third piezoelectric sensor is installed in an aqueous medium and the amplified signal of the second piezoelectric sensor is fed to it in an inverse form, thereby creating a hydroacoustic wave, compensating the hydroacoustic wave formed by vibration of the carrier body.

EFFECT: improved accuracy of information processing.
