Sound Propagation Formulation for 3-D Ray-Trace Computations Spherical Earth.

Abstract

Given the speed-of-sound distribution in the sea the problem is to calculate the trace of a sound ray which leaves a prescribed location in a prescribed direction. The formulation includes the curvature-of-the-earth factor and other curvature terms arising in the selection of horizontal coordinates.
