Finite Element Modeling of Scattering from Underwater Buried and Proud Munitions

Abstract

Develop high fidelity acoustic scattering models to facilitate the detection, localization, and characterization of military munitions found in ponds, lakes, rivers, estuaries, and coastal ocean areas. Use these models to design experiments, interpret collected data, identify features that can be used in training classifiers. The objective of this work has been to develop high fidelity acoustic scattering models that can quickly compute the acoustic color templates (backscattered target strength as a function of frequency and aspect angle) for UXO targets. These models are used to design experiments, interpret collected data and particularly identify features that can be used in classification.
