COMPUTATIONAL MODELING ANALYSIS OF RADAR SCATTERING BY CLOTHING COVERED ARRAYS OF METALLIC BODY-WORN EXPLOSIVE DEVICES

In this study, we address the problem of detecting body- worn improvised explosive devices (IEDs) from a safe distance using radar. We have used a finite difference frequency domain (FDFD) model to simulate the radar signature of a typical scenario for body- worn IEDs, and have analyzed wrinkled clothing as a possible source of clutter, as well as the possibility for uniform versus nonuniform array spacing of explosive-filled metal pipes. Our analysis shows distinct characteristics of the pipe backscattered farfield signal for uniformly spaced pipes, with no significant clutter added when the metallic pipe is covered with wrinkled clothing.
