| 摘 要： | 在浅海环境中,舰船产生的低频水声信号会在海水和海底介质界面处以舰船地震波的形式进行传播1],此时海底具有低通滤波的特性.通过理论分析和使用COMSOL Multiphysics软件的声-固耦合模块建立仿真模型,验证其滤波特性的存在,并讨论不同声源深度对海底地震波传播的影响.

| Abstract: | In shallow sea environment, the low frequency underwater acoustic signal generated by the ship will be transmitted in the form of seismic wave in the interface of the sea water and the seabed medium. At this time, the seabed has the characteristics of low pass filtering. Based on the theoretical analysis and using the sound-solid coupled module ofCOM-SOL Multiphysics software to build the simulation model, the existence of the filtering characteristics is verified. And thein-fluence of different depth of sound source on the seismic wave propagation in the seabed is discussed. |
