Sound radiation by cylindrical hydroacoustic transducer in the presence of a screen with electrically controlled acoustic power

Abstract

The problem of increasing the effi ciency of the sonar station by using a sonar antenna with an active acoustic screen is stated. Electrical control of the acoustic properties of such baffl e can provide a wide range of dynamic capabilities of the acoustic antennaand technical implementation due to this in one sonar station of several modes of its operation. Analitical expressions for quantifying the electrical, mechanical and acoustic fi elds of an antenna with a dynamic change in the parameters of the active screen using the method of coupled fi elds in multiconnected domains are obtained. A qualitative analysis of the infl uenceof individual physical factors and their mathematical analogues in the obtained analytical relations on the dynamic properties of fields are carried out.
