Abstract
Efficient generation of replica fields at high frequency is essential for acoustic tomography or for full field inversions of small-scale bottom roughness parameters. Such roughness can cause scattering of great significance to high-frequency active sonars operating in shallow water. Three-dimensional effects due to rough sloping bottoms can also be important to such sonars. In this paper we present a ray-theoretic method of computing fully coherent pressure fields, consistently in 2-D or 3-D range dependent environments, which avoids calculations of eigenrays or focusing factors. Also, we present 2-D results from a numerical implementation on a massively parallel computer architecture.
