METHOD OF MEASURING COMPONENTS OF TOTAL INTERFERENCE TO WORK OF PASSIVE HYDROACOUSTIC STATION Russian patent published in 2017 - IPC G01S3/80 

FIELD: physics.

SUBSTANCE: invention can be used to determine the components of the total interference affecting the hydroacoustic station (HAS) in order to determine the contribution of each component and their possible reduction. The method is proposed for measuring components of the total interference to the operation of the receiving hydroacoustic system made in the form of a series-connected hydroacoustic antenna located in a ship fairing and a receiving path, in which the energy spectrum of the structural interference component is measured as the difference in the energy spectrum of the interference obtained after evacuation of water from the fairing, and the energy spectrum of the electrical component of the interference, the fairing is filled with water and the ship is located in the dock, the received power interference spectrum is measured, and the energy spectrum of the vibration component of the interference is determined as the result of subtraction from the determined energy interference spectrum, when the vessel was in the dock with the fairing filled, the energy spectrum of the structural component, the interference and the energy spectrum of electrical noise component and the energy spectrum of the noise interference are determined as the difference between the energy spectra of the total interference and the sum of the energy spectra, the structural, vibrational and electrical components.

EFFECT: method ensures the simplicity and efficiency of measuring interference components.
