A Parabolic Equation Propagation Loss Model.

Abstract

A parabolic equation model for the prediction of acoustic propagation loss in a range-dependent ocean has been developed for use on the DRCS IBM 370/168 computer. Use of the model is outlined and several examples given. Particular attention is given to the method of modelling the bottom interface reflection process, and to appropriate choice of FFT size.
