Computer Models of the Human Body Signature for Sensing Through the Wall Radar Applications

Abstract

This technical report presents numerical simulations of the human body radar signature, with application to sensing through the wall (STTW) scenarios. We utilize the Finite Difference Time Domain (FDTD) modeling technique to compute the electromagnetic scattering from realistic human body models. We analyze the radar cross section (RCS) of the human body in different configurations as a function of aspect angle, frequency, and polarization, drawing important conclusions in terms of the magnitude, variability, and statistics of the human radar signature. We also use the modeling data in order to simulate the operation of a low frequency, ultra-wideband (UWB) synthetic aperture radar (SAR), by creating SAR images of the human body in various configurations. The results obtained in this study can be used as guidance by radar system designers in order to optimize performance in the context of a STTW scenario.
