Unified Description of Scattering and Propagation FY13 Annual Report

Abstract

The long-term goal of the research is to increase the physical understanding of acoustic propagation and scattering 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. For FY13, the first objective was to investigate the statistics of the mode intensity and cross-mode coherence that result from scattering from a randomly rough seabed surface in a shallow water environment. The second objective was to extract information about the frequency dependence of seabed attenuation for a soft thick sediment.
