Computational Modeling Analysis of Radar Scattering by Metallic Body-Worn Explosive Devices Covered with Wrinkled Clothing

In this study, we address the problem of detecting body-worn improvised explosive devices (IEDs) from a safe distance using of 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. Our analysis shows distinct characteristics of the IED backscattered farfield signal, with no significant clutter added when the metallic IED is covered with wrinkled clothing.
