摘　　要：用激光在海洋中产生声波的方式机动性非常好,在海洋监测方面具有非常强的潜在应用前景。介绍了已经成功研制出的一套可以用于水下目标探测的激光声技术实验系统,详尽地介绍了用于水下目标探测的激光声系统原理、硬件设计以及软件设计。该系统不仅通过了实验室的试验,并且参加了海上试验,实验结果表明本系统的原理正确,性能良好,工作稳定可靠,能够检测到水中目标的回波,探测到水下目标。说明激光声技术用于水下目标探测是切实可行的,这套激光声探测系统的研制成功填补了国内的空白。Using laser to generate acoustic wave in the sea has much flexibility, and can be potentially applied to sea monitoring. An experimental system for target detection of using laser-acoustic technology in the .sea is set up. The fundamental principle of laser-acoustic detecting target and the system hardware and software design are described in detail. The experimental results at both laboratory and sea prove that the fundamental principle is right, and that the performances of the hardware and the software of the system are reliable and exceUent, and can detect the echo of the object in water. The experimental results also show the feasibility of laser-acoustic technology.
