摘要
根据声传播在浅海多次海底-海面反射的传播规律,以及海底切变波效应对浅海声传播的影响,分析了舰船地震波场的形成机理和理论传播模型,并通过对舰船地震波场的实验测量方法的讨论和具体实验数据的分析,研究了舰船地震波场的传播特性和频谱特性。
According to the transmission characteristics of the acoustic wave in shallow ocean, and considering the influence of bottom shear wave,a reasonable model of the ship＇s seismic waves field is introduced to explain the process how the field come into being and transmit. Through the experiment of ship＇s seismic wave field and the data analysis, the transmission and frequency characteristics of the ship＇s seismic wave field are figured out.
