中文简介: | 本课程考察了流体和粘弹性介质的波动方程,声源辐射的波动理论公式和分层海洋波导中的地震声传播,以及平面分层介质中传播的波数积分和正常模式方法。还介绍了海底和冰盖的Seismo-Acoustic建模,分层海床中的地震界面和表面波,抛物线方程和耦合模式在距离依赖的海洋波导中的传播方法,海洋波导中目标散射和混响杂波的数值模拟,和海洋环境噪声建模。学生使用与最先进的声学研究相关的所有数值方法开发传播模型。本课程最初在课程13(海洋工程系)中提供,为13.853。 2005年,海洋工程学科成为课程2(机械工程系)的一部分,该课程重新编号为2.068。 |
课程简介: | This course examines wave equations for fluid and visco-elastic media, wave-theory formulations of acoustic source radiation and seismo-acoustic propagation in stratified ocean waveguides, and Wavenumber Integration and Normal Mode methods for propagation in plane-stratified media. Also covered are Seismo-Acoustic modeling of seabeds and ice covers, seismic interface and surface waves in a stratified seabed, Parabolic Equation and Coupled Mode approaches to propagation in range-dependent ocean waveguides, numerical modeling of target scattering and reverberation clutter in ocean waveguides, and ocean ambient noise modeling. Students develop propagation models using all the numerical approaches relevant to state-of-the-art acoustic research. This course was originally offered in Course 13 (Department of Ocean Engineering) as 13.853. In 2005, ocean engineering subjects became part of Course 2 (Department of Mechanical Engineering), and this course was renumbered 2.068. |
