Acoustic Coherent Backscatter Enhancement from Aggregations of Marine Animals

Abstract

The overall long-term goal for this project is to determine if and how acoustic coherent backscatter enhancement (ACBE) can be used for classification of active sonar returns in a wide variety of ocean environments. During its first twenty months, this project has focused on simulations of acoustic multiple scattering from aggregations of omni-directional point scatterers to determine the parametric realms in which ACBE might be observed, and its characteristics when it is observed.
