Abstract
A sonar transducer includes an electro-mechanical transducer coupled to a front mass and a back mass. Annular rings space a compliant diaphragm from the front mass, the diaphragm being in communication with the liquid to which the sonar transducer is exposed. The compliance of the diaphragm is selected to tune the sonar transducer to eliminate reactive components of the impedance of the combined sonar transducer and liquid medium load, and to maximize the radiation resistance of the system.
