The Two Dimensional Numerical Modeling Of Acoustic Wave Propagation in Shallow Water

摘要

This paper describes progress on a two dimensional numerical simulation of acoustic wave propagation that has been developed to visualize the propagation of acoustic wave fronts and to provide time-domain signal representation in shallow water. It is intended that an extension of the work presented here, to account for three-dimensional effects, will later be compared with field results. The numerical simulation of shallow water acoustic propagation has given rise to a wide variety of modeling techniques with various degrees of accuracy. One technique, involving finite difference methods, is more commonly used in the description of seismic propagation but also occurs in the shallow water propagation literature. This word reported here involves the application of finite difference techniques to model propagation in the time domain, together with associated code to allow wave front visualization.
