Abstract

Abstract

A method of sound propagation in a range-dependent underwater environment is presented. This method is based on the coupled mode-parabolic equation method(CMPE) and the normal mode solution is carried out with the aid of Galerkin's method. The sound fields both in water volume and sediment are predicted. The numerical examples are given to illustrate the accuracy of CMPE with Galerkin's mode solution.
