Analysis of 3-D Propagation Effects Due to Boundary and Volumetric Environmental Variability

Abstract

The goals of this work were multi-faceted, consistent with the various efforts supported by this work. Particular focus was placed on predictions and analysis of the three-dimensional (3-D) scattering from two-dimensional (2-D) rough ocean surfaces. In collaboration with Dr. David Thomson (Canada), additional modeling efforts were undertaken to examine the accuracy of the treatment of the bottom density discontinuity. By continuing to expand and improve the capabilities of the numerical modeling methods, the long-term goal of this effort is to provide a useful tool for understanding the physical phenomena leading to variability in shallow water acoustic propagation. The overall objective of this work was to study the response of the acoustic field in the presence of environmental variability, and to examine the effects of rough surface scattering and bottom topography on shallow water propagation.
