摘　　要：A design of a kind of sonar transducers was presented. An experimental system was developed for producing the sound signal based on the laser-induced breakdown and bubble oscillation. The power spectrum and the ambiguity function were analyzed. The range resolution and the Doppler resolution constant of the sound signal were determined. It is basically proved in theory that both the range resolution and directivity of the sonar transducer are very high. The transducer can be a sound source of high-resolution sonars.A design of a kind of sonar transducers was presented.
