| 摘 要： | 提出一种声呐发射换能器的设计思路。设计激光声产生系统,获取并测量激光声信号,求出激光声信号的功率谱、模糊函数、水中的距离分辨力、多普勒分辨常数。基于激光声的产生、传播、时域波形和频率特性提出声呐发射换能器的概念性设计思路。从理论上初步证明了该换能器具有良好的距离分辨力和指向性,可作为高分辨力声呐的声源。

| Abstract: | A design of a kind of sonar transducer is presented.An experimental system is developed for producing the sound signal based on the laser-induced breakdown and bubble oscillation.The power spectrum and the ambiguity function are analyzed.The range resolution and the Doppler resolution constant of the sound signal are 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 the sound source of high resolution sonars. |
