Electromagnetic Scattering Effects of Sea on the Radar Cross Section (RCS) of Small Boats in Littoral and Deep Ocean Environments.

A comprehensive approach is proposed to providing realistic geometric models for small craft moving in a littoral environment, including representations for the sea surface, suitable for use in computing radar returns from the combined surfaces using currently available electromagnetic solvers. In the phase I effort, HyPerComp, Inc., in collaboration with Prof. Patrick Lynett of Texas A&M University, will construct and demonstrate an interface that utilizes the output of Prof. Lynett''s COULWAVE software, which generates time-dependent sea surfaces representative of both shallow and deep-water conditions, in combination with HyPerComp''s sophisticated gridding tools, to provide complete surface-patch representations for the target environment. In later phases, this interface will serve the basis for writing a GUI that will allow the end user to specify a wide range of sea and target environments for the EM solvers.
