AbstractAccurate prediction of scattering and radiation behavior for broadband (tens of MHz to 20 GHz)) electromagnetic illumination over stationary and mobile ground targets with realistic material treatments in general terrain settings is a critical technology for Combat Identification (CID). The complete problem that needs to be modeled for air-to-ground signature database is electrically very large since one will have to consider all the interactions of incident illumination through foliage penetration, multibounces from the lossy ground plane, various ground scenes, and the ground target. Based on HyPerComp's strengths in CAD modeling and repair, and in high order algorithms for time-domain Maxwell's equations, we plan to team up with SAIC-DEMACO and propose to link TEMPUS (Time-Domain EM Parallel Unstructured Simulator) with clutter model routines and the high frequency Xpatch code through a hybridization process called CrossFlux to provide phenomenology modeling of scattering from stationary and moving ground targets.
