MULTIPLE-UNIT HYDROACOUSTIC ANTENNA Russian patent published in 2009 - IPC G01S7/52

Abstract SU 1840774 A1

FIELD: radio engineering.

SUBSTANCE: invention relates to radio engineering filed and can be used in echo-ranging sonars. Device contains set of pivotal piezoelectric converters, fixed on common plate. Gap between transformers and doubled thickness of plate, on which there are fixed transformers, there are implemented smaller than a length quarter of longitudinal wave in plate.

EFFECT: providing of scanning effective of antenna diagram.
