Radar Signature Tools for Small Boats in Dynamic Sea Environments

A comprehensive approach is proposed to develop and integrate tools for computationally obtaining radar signatures of small watercraft in dynamic seas over many simulation steps. In the proposed Phase I effort, HyPerComp, Inc. will develop and demonstrate capabilities for quickly creating geometric representations of dynamic sea states with boats in motion for use by high frequency and full wave electromagnetics solvers. A template-based or parameterized approach to creating boat geometry will be implemented that will allow for fast automated meshing, which will be performed on-demand, based on simulation results and requirements. An advanced 6 degree of freedom (DOF) algorithm will be implemented to accurately predict boat motion due to dynamic seas. Phase II work will focus on further developing the capabilities implemented under Phase I as well as adding or integrating capabilities for visualizing input conditions and large scale simulation results as well as building up a database of boat models and components.
