Underwater Sound Mathematical Model.

Abstract

A general ray theory mathematical model of beam formation and underwater sound propagation over short to moderate ranges is described. Principally, the model was designed as an analytical tool to support in-water performance measurements of typical Naval cylindrical and spherical transducers. However, the performance of linear, planar, and most other array configurations may also be studied. The term 'predicted performance,' as used here, specifically relates to the sound pressure fields in the near, far, and transition-zone regions of the arrays. The model provides for the treatment of reflective path conditions such as those that exist when signals arrive by surface-reflective, bottom-reflective, and direct paths. (Author)
