RECEIVING HYDROACOUSTIC ANTENNA AND METHOD OF ESTIMATING AMPLITUDE-FREQUENCY CHARACTERISTICS OF HYDROACOUSTIC RECEIVERS Russian patent published in 2013 - IPC G01S7/00 H01Q21/00 

FIELD: radio engineering, communication.

SUBSTANCE: receiving hydroacoustic antenna consists of a computer unit and hydroacoustic receivers rigidly mounted on a chassis, wherein a wideband mechanical vibrator is mounted on said chassis and vibrations thereof are transmitted to the chassis during diagnosis, and said vibrator is controlled by commands from the computer unit. Mechanical vibrations of the antenna chassis caused by the vibrator at points where hydroacoustic receivers are mounted are defined and known in advance. During operation of the vibrator, the computer unit measures output signals of hydroacoustic receivers, based on which operating capacity thereof is determined and amplitude-frequency characteristics are determined. This allows rapid inspection of operating capacity of hydroacoustic receivers and measurement of amplitude-frequency characteristics thereof in order to derive adjustment factors.

EFFECT: enabling rapid inspection of operating capacity of sensitive antenna elements and plotting of amplitude-frequency characteristics of hydroacoustic receivers.
