航行舰船地震波及其在水中目标探测中的应用
|
摘要
从理论上论述了浅海波导中发生声波显著透射进海底从而造成水中传播声信号严重衰弱的原因,通过对已有的海底声传播研究实验数据的分析和总结,阐述了航行舰船地震波的产生和传播的基本规律,提出和论证了航行舰船地震波在水中目标探测中的重要应用前景和价值。
In this paper, firstly the theoretical reasons of sound penetration into the sea bottom that causing the degradation of the waterborne sound is presented. Secondly the way how the seismic wave is induced by the ship and how the seismic wave is propagated is described through analyzing the experiment data. Finally some important application of the ship induced seismic wave in the underwater target detection is presented.
