SELF-CONTAINED HYDROACOUSTIC DEVICE Russian patent published in 2010 - IPC G01S15/04 

FIELD: physics.

SUBSTANCE: self-contained hydroacoustic device has a girder, a platform which is also an anchor, a container as a coupler for switching cables of the acoustic antenna with main cables, an acoustic antenna with the required coverage area and electronic apparatus. The acoustic antenna is sectional, and the self-contained hydroacoustic device has four modifications which are fitted with a different number of acoustic antennae, which provide the following coverage areas in the horizontal plane; first - having six acoustic antennae with a 360° coverage area, a second - having three acoustic antennae with a 180° coverage area, a third - having two acoustic antennae with a 120° coverage area, fourth - having one acoustic antenna with a 60° coverage area, where the next three modifications have only a different number of acoustic antennae and different standard size of suspension plates, respectively, and each suspension of the stand-alone hydroacoustic has a cardan mechanism which enables rotation of suspension with the acoustic antenna about two horizontal axes by an angle ±25°±2°.

EFFECT: improved method.
