The Acoustic Signatures of Proud and Buried Mine-like Objects and Their Temporal Variation

Abstract

My long term goal is to understand, for different environments, the biological and hydrodynamic processes important to the changes seen in the acoustic scattering from proud and buried mines as a function of time after deployment. My objective in this effort is to process and interpret acoustic monitoring data taken on both mine shapes and localized biological treatments during the 1995 ORCAS experiment. The ORCAS data allows examination of the acoustic scattering from mines and biological treatments for up to two months. Four types of results can be produced using the data: backscattering, scan-to-scan decorrelation, cumulative decorrelation relative to a reference scan, and bathymetry. The goal is to examine the results in combination to quantify, interpret, and guide future research on the temporal variations of scattering from bottom deployed mines. Of particular interest to me are the temporal variations of scattering from buried objects.
