Effect of Suspended Sediment on Acoustic Detection Using Reverberation

Abstract

Sonar operates by ensonifying a broad swath of the seabed using a line array of acoustic projectors with acoustic backscattering from the ensonified sediment. The suspended sediment layer affects the sonar imagery through the volume scattering strength. Understanding the acoustic characteristics of the suspended sediment layer can aid the Navy in detecting sea mines with sonar imagery. In this study, the Navy's Comprehensive Acoustic Simulation System is used to investigate such an effect. A range of critical values of volume scattering strength for buried object detection is found through repeated model simulations.
