A Ray Tracing Model for Propagation Loss Calculations.

Abstract

A brief description is given of a ray tracing model developed for making propagation loss predictions for use in underwater acoustic research. A range independent sound speed profile and ocean depth are assumed. The various options available to the user are discussed together with some results, which highlight the importance of having available good bottom loss versus grazing angle data. A FORTRAN computer programme is currently available for use on the IBM 370/168 at Defence Research Centre Salisbury. (Author)
