摘要
水下等离子体声源作为一种大功率水下脉冲声源,具备诸多优点,对于海洋资源开发及海上军事防务具有重要的战略意义。介绍了水下等离子体声源的基本原理、产生方式及定向聚焦技术,给出了水下等离子体声源的试验装置,详细地研究了系统各部件的设计原则和各个部件的参数配置,展望了水下等离子体声源的发展前景。本文结果来源于大量的水下等离子体声源设计经验。
Underwater plasma sound source acting as a high-power controllable sound source has many advantages, and been more and more widely applied to exploit resource under the sea and potential in military realm. Its acoustic efficiency is one of the focuses of the issues. This paper presents the techniques of high-power underwater shockwave generation, microcosmic mechanism of underwater plasma, and directional radiation of underwater sound pulse. The design principle of each part of underwater plasma discharge system and the configure scheme of system parameters were particular researched. Some key components of these test devices are designed in detail. Finally, the application of underwater plasma sound source is discussed. The research in this paper accumulates lots of ex- perience about underwater plasma sound source design.
