Abstract:

This report describes mathematical, numerical, and software design methods for ray models for range dependent ocean environments. Numerical techniques are described for solving ray path and intensity differential equations and for computing path length and travel time integrals. Modified cubic splines fit the bathymetry and sound speed profiles with the degree of mathematical smoothness required to eliminate false caustics and shadow zones, while avoiding non-physical excursions sometimes observed in standard splines. Several new interpolation procedures yield eigenray path information.
