The acoustic velocity, density and thickness of the matching layer were adjusted to analyze the acoustic characteristics of the transducer, including syntonic frequency, transmitting voltage response, receiving sensitivity of free field voltage, and receiving transmitting frequency bandwidth, and to optimize its structure. Tank test of the transducer was conducted, and the results agreed well with computation. This study may offer a reference for sonar array design.
