High-Fidelity, High-speed, 3-D Finite-Element Modeling of Acoustic Scattering From Objects in Shallow Water

Abstract

The goal is to bring to fruition R&D that has been performed for ONR since FY05. The work has involved the development of a state-of-the-art, high-fidelity, high-speed, 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). Many of the computational techniques developed in this effort will be relevant to future ONR programs involving different applications.
