Sound Propagation in the Sea -- Ray Tracing. The Wave-Front-Divergence Factor in Ray-Intensity Integration.

Abstract

The report performs the mathematical analysis necessary to add divergence loss in differential form to the ray-trace program. The analysis is to: pertain to a two-dimensional x, z plane formulation; express intensity change in decibels; be adaptable to 100, 10 000, 100 000 yard and longer ranges; and include finite-difference approximations for numerical integrations.
