On the use of two-dimensional orthogonal function expansions to model ocean bathymetric and sound-speed data in the recursive ray acoustics algorithm

The two dimensional orthogonal function expansion technique was used to model discrete ocean bathymetric data as a function of cross range and down range, and to model discrete sound speed data as a function of depth and down range. The technique was tested and validated via computer simulation. It...
