Ultrawideband SAR for detection of subsurface unexploded ordnance (UXO): measurement, modeling and signal processing


Journal Article

We report here on the use of rigorous scattering models for SAR-based detection of buried UXO. In this paper we concentrate on the algorithm used for the scattering computations, the fast multipole method (FMM), and in the talk we will demonstrate how this is applied to subsurface-target detection, using data from the Army Research Laboratory BoomSAR. The fast multipole method (FMM) is applied to scattering from an arbitrary, three-dimensional perfect conductor situated above or below a lossy, dielectric half space. Example results are presented for an electrically large target buried in a lossy, dispersive half space, with comparisons presented between the FMM and a rigorous method of moments solution.
