The Impact of Range-Dependent Sediment Properties on the Acoustic Field in 2-D Shallow Water Environments

Abstract

The goal of this research is to understand the effects of range-dependent sediment properties on the acoustic field in 2-D shallow water environments. This information, in part, is required to solve the statistical inference problem in inhomogeneous shallow water environments. The objective of the current work is to create and benchmark a two-way coupled mode model that will later be used to analyze the effects of range-dependent sediment properties on the acoustic field in typical littoral environments. An accurate coupled mode model is required to properly capture the physics of shallow water acoustic propagation and to classify the propagation as belonging to either the adiabatic or coupled mode regime. It is of particular interest to classify acoustic data taken during the Shallow Water 2006 (SW06) experiment as being adiabatic or coupled mode and to identify the physical mechanisms that cause mode coupling.
