Alternate Title

Body-worn improvised explosive device detection using millimeter-wave radar

Abstract

Amidst the manifold threats currently afflicting public welfare, that of body-worn explosives is significant if not altogether paramount. Commonly referred to as ""suicide bombers,"" the bearers of body-worn, improvised explosive devices (IEDs) enter crowded public areas in order to detonate the IDE, inflicting lethal damage to themselves and surrounding individuals. Constructed of non-standard parts and veiled under layers of clothing, these body-worn IEDs go frequently undetected. The aim of this research is to examine the feasibility of using millimeter-wave (MMW) radar to detect body-worn IEDs at distances up to 50 meters. In order to achieve a beamwidth capable of illuminating a single human at 50 meters, which in this case would be approximately 0.01 radians, while still maintaining a practical aperture size, we require a wavelength on the millimeter scale. The radar made available for testing, provided by Raytheon, operates at 77GHz. At a wavelength of 3.89mm, this radar provides, at a testing distance o 10.1 meters, an adequate simulation of a human-torso-sized beamwidth at 50 meters. This research also examines the role of the Gregorian Dual Confocal Reflector antenna in achieving smaller beamwidths from apertures of limited size.
