HYDROACOUSTIC RECEIVING UNIT Russian patent published in 2013 - IPC G01S15/00 

FIELD: radio engineering, communication.

SUBSTANCE: hydroacoustic receiving unit consists of a system for mounting the hydroacoustic unit to the shape-forming frame of a hydroacoustic antenna, a hydroacoustic receiver and a hydroacoustic screen connected thereto, wherein the hydroacoustic screen is rigidly mounted on the rear side of the hydroacoustic receiver. The hydroacoustic receiver itself is connected to the hydroacoustic unit mounting system through a rod which is coaxially inserted into a pipe which is rigidly connected to the hydroacoustic unit mounting system, the rod being mounted in the pipe by dowels made from vibration-insulating material to provide vibration-insulation of the receiver from structural noise of the carrier transmitted through the rigid mounting from the shape-forming frame of the antenna. The pipe and rod freely pass through a through-hole in the hydroacoustic screen and enable the screen to be freely deformed without changing the geometry of the arrangement of the receiver on the shape-forming frame of the antenna.

EFFECT: high accuracy of positioning hydroacoustic sensors owing to the invariance of the geometric arrangement of the sensors relative the frame of the antenna.
