Abstract:

The long-term goal of the research is to increase the physical understanding of acoustic propagation in continental shelf and slope environments in the 50-4000 Hz band. This includes both the physics of the seabed and the coupling to physical mechanisms in the water column in complex range- and azimuth-dependent littoral waveguides. There were two main objectives of the current research. The first objective was to develop and test a new coupled-mode approach that can serve as the basis for an advanced seabed attenuation analysis of broadband propagation data. The second objective was to apply the coupled mode approach to investigate the physics of scattering from a rough seabed surface.
