A CONTINUOUS GRADIENT RAY TRACING TECHNIQUE.

Abstract

A method of computing ray paths in an ocean for which the velocity gradient varies continuously with depth was developed. The ocean is divided into several horizontal layers. In each layer the velocity-depth profile is given by a four-parameter curve that permits range and travel time integrals to be evaluated in closed form. The curve fitting and ray tracing equations can readily be incorporated into computer programs. Some of the advantages of this technique and other ray tracing methods are compared. (Author)
