Ultra-wideband Radar for Building Interior Imaging

Abstract : This paper presents both numeric simulations and radar measurements related to through the wall imaging technologies. We present synthetic aperture radar (SAR) images obtained by the Army Research Laboratory (ARL) Forward-Looking Radar system during field experiments and compare those with the results of our Xpatch computer models. We also demonstrate a computational approach based on the Finite Difference Time Domain (FDTD) algorithm in order to obtain the SAR images of a complex room. Our goals are both to validate the numerical simulations techniques and to understand the radar scattering phenomenology in this environment.
