ANTENNA MODULE WITH DIGITAL OUTPUT Russian patent published in 2015 - IPC H04R1/44 

FIELD: radio engineering, communication.

SUBSTANCE: disclosed is an antenna module design with a digital output, comprising single-row (or two-row) acoustic antenna array and a sealed container which houses a signal preprocessing unit with data compression and a common cowling with filling of the gaps between the antenna and the cowling, as well as between rows of the antenna with an elastomer. In said single design, the antenna is not connected by mechanical fastening elements to the housing of the carrier, which reduces the level of structural interference on the antenna and provides integrity of the back coating on the housing of the carrier. Filling the gap between the cowling and the antenna with an elastomer damps the cowling and reduces the level of flexural waves arising when the cowling is exposed to hydrodynamic interference.

EFFECT: said conditions, coupled with high noise-immunity of the antenna module when exposed to electromagnetic interference, enables to create a noise-immune structure which is easy to manufacture and install on a carrier, having fewer cables in the main housing.
