SUPPLEMENTARY NOTES
ABSTRACTThis technical report presents numerical simulations of the ultra-wideband (UWB) radar return from a simple room with a human inside, with application to sensing through the wall (STTW) radar scenarios. We use the Finite Difference Time Domain (FDTD) and Xpatch modeling techniques to compute the range profiles of the room at specific incidence and observation angles. Our goal is to analyze the electromagnetic phenomenology in operating an UWB radar for STTW applications. At the same time, we are interested in understanding issues specific to these computational techniques as applied to this type of problems, as well as validating Xpatch as an accurate tool for modeling general STTW radar scenarios.
