海底声学参数反演方法研究

The research on methods of seafloor parameters inversion

声波是惟一在水下远距离传播的能量形式。海底沉积物的声速、密度、衰减系数、分层结构等声学参数是浅海声场数值预报、匹配场定位、潜艇沉底隐蔽地点选择等应用中所必须的参数。给出了目前比较有效的同时也是国际上海底声学参数反演的一些较新的方法。

Acoustics is the only propagation energy for long distance underwater. The acoustical parameters, like velocity, density, attenuation, structure, et al, are very important for the sound field prediction in shallow water, location of MFP and covert selection of submarine. This paper gives some methods of ocean floor acoustic parameter inversion.
