Multi-Level Fast Multipole Algorithm w/ Application to Foliage Penetrating Radar

Abstract

This project has involved both numerical simulation of electromagnetic scattering for ultra-wideband synthetic aperture radar (SAR) for foliage and ground penetrating radar (FOPEN and GPEN, respectively). We have developed a fast multipole method (FMM) model for electromagnetic scattering from electrically large conducting targets in the presence of a half space, with application to scattering from surface/subsurface unexploded ordnance (UXO), as well as for scattering from surface vehicles, such as tanks. The FMM simulator is significantly faster than conventional method-of-moments (MOM) solvers. allowing solution of problems that were heretofore intractable. The code has been delivered to the Army Research Laboratory (ARL), and successfully compared with data measured by ARL.
