Abstract:

The goal is to bring to fruition RD 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 watersediment interfaces Fig. 1. Many of the computational techniques developed in this effort will be relevant to future ONR programs involving different applications.
