Hybrid raytrace modelling of an underwater acoustics communication channel
2004 (English)In: Proceedings of the Seventh European Conference on Underwater Acoustics, 2004, 1211--1216 p.Conference paper (Refereed)
A hybrid method is described for modelling sound propagation in range-dependent shallow water environments. The method combines ray tracing in a range-dependent water column with local full-field modelling of interactions with a seabed composed of multiple range-dependent layers of fluid or solid materials. The method is assessed by simulations of the Yellow Shark 94 experiments in the Mediterranean, using environmental parameters available from previous acoustic full-field inversions of the experimental acoustic data, and from an oceanographic survey with a towed-oscillating CTD profiler. Results from applying the method to simulation of transmission and decoding of communication signals in the shallow-water waveguide are presented.
