Abstract
The high frequency transducer usually has a narrow working band which limits the underwater target detection performance of high-frequency sonar. Matching layer is an important technology to expand the working band. Due to the complex manufacturing process, previous researches are mainly based on simulation results. In this study, a series of transducer with matching layer were made, and the admittance were measured both in air and in water, The influences of matching layer thickness on the performance of transducer were obtained, which is useful for the optimal design of high frequency transducer. Under the optimal matching layer thickness, the bandwidth of the transducer exceeded 60kHz with the center frequency of 115kHz.
