Parallel-Processor-Based Gaussian Beam Tracer for Use in Ocean Acoustic Tomography.

摘要

This thesis presents a parallel processor band acoustic ray tracing algorithm for use in predicting multipath arrival times and amplitudes, for use in ocean acoustic tomography experiments. The Runge-Kutta-Fehlberg numerical integration method was chosen, out of three other methods, to numerically solve the ray equations. Cubic splines were used to interpolate the sound speed profile and bottom bathymetry data. The method of Gaussian beam tracing was used to compute the multipath amplitudes at a given receiver location. The ray tracing algorithm is written in C, and is designed to run using a Macintosh II-based host application and a transputer based, parallel processing workfarm.
