Geological and Geophysical Reconnaissance for the ONR Geoclutter Program

Abstract

The common goals are to: 1) understand the acoustic scattering process in shallow water, with the objective of designing physics-based signal processing algorithms to distinguish naturally-occurring features (e.g., iceberg scours, shallow gas accumulations, outcrops of high-amplitude shallow subsurface reflectors, shallowly-buried meandering channels) which are ubiquitous on the world's continental shelves, so-called geoclutter , from man-made targets of similar dimensions (e.g., submarines), and 2) to predict the distribution and properties of geoclutter at a chosen U.S. continental margin test site, with eventual application to other continental shelves of Navy interest globally.
