MULTIELEMENT HYDROACOUSTIC ANTENNA

摘要

FIELD: data processing.SUBSTANCE: invention can be used for reception of digital data in a multibeam hydroacoustic communication channel with marked effect of signal fading caused by acoustic beams interference; essence: the antenna is made of separate receiving elements in the form of thin-wall of the piezoceramic rings with wide frequency band and a circular beam pattern in horizontal plane, mouthpieces of conical shape separated vertically, which form separate receiving area at angles of arrival of beams with non-coincident time fading control signal amplitude.EFFECT: increase of communication channel resistance against interference of multibeam and reverberation.1 cl, 2 dwg
