HYDRO-ACOUSTIC RECEIVING ANTENNA Russian patent published in 2006 - IPC H04R17/00

Abstract SU 1840336 A1

FIELD: hydro-acoustics, possible use for engineering receiving hydro-acoustic antennas, their sections and blocks.

SUBSTANCE: hydro-acoustic antenna consists of sections, containing electrically synchronized piezo-electric receiving elements. Sections of antenna are made of even number of elements, while polarizations of adjacent elements have opposite directions.

EFFECT: increased interference resistance of antennas to electromagnetic pickups.
