Abstract

FIELD: hydro-acoustics.SUBSTANCE: antenna contains rod electro-acoustic transformers, held on common receiving-emitting piece, and also is provided with additional metallic plate, adhesively fastened to receiving-emitting piece across its whole external surface by means of intermediate layer of polymer material, while thickness of metallic plate is 0,01-0,02 of wave length at central working frequency, and thickness of intermediate layer is connected to thickness of metallic plate by following ratio:where i=0,1,2 - indexes, related respectively to substance, metallic plate and intermediate layer,- wave number; λ- wave length at central working frequency; l- thickness of layer;ρ- density of layer material; C- speed of sound in material of layer.EFFECT: decreased level of side leaves in wide range of frequencies.3 dwg
