Acoustic properties of the deep screened sonar radiator

Abstract

The necessity of application of rigid type acoustic screens in hydroacoustic stations with deep-water antennas of variable depth is substantiated. By the method of coupled fi elds in multiconnected regions for antennas formed from cylindrical piezoceramicradiators with rigid screens in the form of open rings of fi nite thickness, analytical expressions for calculations of acoustic fi elds of such radiators are obtained. In the solution of the problem “pass-through” radiation shielded transducer included interactions: electrical, mechanical and acoustic fi elds in the conversion of energy; acoustic fi elds of the shell and screen during energy generation; processes of energy conversion and formation. Quantitative results of calculations of acoustic fi elds on the received expression are resulted.
