Propagation and scattering in very shallow water

摘要

Over the past several years COASTSYSTA has developed a sonar simulation for modeling sonar performance in very shallow water and the surf zone called PC SWAT (Personal Computer Shallow Water Acoustic Tool-set). The latest version of PC SWAT (7.0) is scheduled for release in September of 2001. It includes propagation in a 3-dimensional environment, a time-varying sea surface, a model for the evolution of bubble clouds in the surf zone, 3-dimensional targets, and coherent imaging capabilities. This article focuses on some of the new features that have been added to PC SWAT during FY 2001.
