Abstract:

Many ray tracing programs allow for a sloping or structured bottom but completely ignore the fact that the vector normal to the bottom can have an out-of-plane component. To ignore this in long range propagation over irregular bottoms is to assume cylindrical symmetry of the bathymetry about the source, a condition rarely realized in at-sea experiments. This paper describes a preliminary effort to devise and apply a numerical technique to demonstrate the three-dimensional effects of ray tracing over actual seamounts, ridges and basin walls. Author
