Sediment Acoustics: Wideband Model, Reflection Loss and Ambient Noise Inversion

Abstract

Physically sound models of acoustic interaction with the ocean floor including penetration, reflection and scattering in support of MCM and ASW needs. Objectives: (1) Consolidation of the new BIC08 model of sediment acoustics, its verification in a variety of sediment types, parameter reduction and documentation in preparation for transition. (2) A new model of sediment reflection based on a mixture of models suitable for shallow water sonars for transition to NAVO. (3) Coupling of BIC08 to rough surface scattering models.
