Physical fields of circular cylindrical sonar antennas with scattering screen and cylindrical piezoceramic transducers
Main Article Content
Abstract
The problem of sound radiation by circular cylindrical antennas formed from a cylindrical piezoceramic transducers with circular polarization with compensated and uncompensated design and acoustically soft cylindrical scattering screen in the inner cavity has been solved using the related fields method in multiply connected areas. The solution made in consideration of the interaction of electrical, mechanical and acoustic fields in the process of converting electrical energy into acoustical and interaction between the scattering screen and transducers in the acoustic field of the antenna caused by multiple scattering of sound on the antennas elements. The analytical expressions, allows us to provide numerical calculations of the parameters of the antennas of this type with the actual physical features of antennas.
