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 watersediment 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 RD 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.
