DIGITAL COMPOSITE VECTOR RECEIVER WITH SYNTHESISED CHANNELS Russian patent published in 2014 - IPC G01S15/02 

FIELD: radio engineering, communication.

SUBSTANCE: receiver is designed to carry out vector-scalar measurements of parameters of hydroacoustic fields in seas and oceans. The receiver has a housing with an inertial mass situated at the centre of the housing, six analogue-to-digital converters, a microprocessor and three measurement channels, the axes of sensitivity of which lie in space according to axes of an orthogonal coordinate system. Each of the channels consists of two sensitive elements which are made of piezoceramic and are mounted opposite each other. One end of the sensitive elements holds the inertial mass and the other end rests on the housing. Each sensitive element is connected to the input of its analogue-to-digital converter, output codes of which are transmitted to the microprocessor device.

EFFECT: compensating for difference in electroacoustic transfer constants of sensitive elements of a receiver, which reduces cross sensitivity of the disclosed receiver and improves the beam shape, structural and process simplification by excluding separate sensors of the hydrophonic channel and simple technology of making the housing of the receiver.
