High-Fidelity Finite-Element Structural Acoustics Modeling of Shallow-Water Target Scattering

Abstract

The goal of this three-year effort is to develop a state-of-the-art, high-fidelity, finite-element, broadband computer simulation capability for modeling the scattering of sonar signals by undersea mines located in or near the seabed in littoral environments with smooth or rippled water/sediment interfaces. The target models will include all internal and external structural details that significantly affect the scattered field. The primary objective is to provide the U.S.Navy with a state-of-the-art MCM simulation tool, readily available to scientists at any laboratory, on virtually any computer platform, at modest cost. A secondary objective is to maintain a continuing R&D effort in order to significantly increase the computational efficiency of the software, thereby expanding the ability to model more complex targets, at higher frequencies and over broader bands.
