A FORTRAN Code for the Calculation of Sound Propagation in a Range Dependent Ocean Volume II. Range Functions and Mode Coupling.
Abstract
Pierce's adiabatic normal-mode theory of sound propagation in a range dependent ocean duct is extended to the case of a sound channel with less than gradual range dependence. A computational method is devised to solve the ensuing coupled range equations by diagonalization. This is applied to a channel with arbitrary (numerically given) range dependence, by dividing it into range segments with constant properties each. The local depth functions are taken as the Airy function solutions in a piece-wise linearized stratified medium with arbitrary sound velocity profile. The method is applied to some simple as well as to realistic cases of range dependent sound channels, and the dependence of the mode coupling effects on the degree of range dependence is determined.
