Finite-Element Modeling of Acoustic Scattering from Objects in Shallow Water

Abstract

The goal is to develop a state-of-the-art, high-fidelity, 3-D, finite-element (FE), broadband computer simulation capability for modeling the scattering of sonar signals by undersea objects located in or near the seabed in littoral environments with smooth or rippled water/sediment interfaces (Fig. 1). It is expected that most of the general computational techniques being developed in this effort will be able to be used in future ONR programs involving different applications
