Abstract

Acoustic transducers are the popular elements for sonar array. The transducer of the simplify electrical equivalent circuit is discussed, and a impedance measurement system is developed to estimate the elements value of transducer's lump circuit model at or near resonance. For practial application, a matching transformer is designed to make the transducer a high efficiency and high power transmitter. The experiment result approves the. Impedance Measurement Approach is the effective method for high power acoustic transducer development.
