Hand-held microwave search detector

Initial experiments have shown that plastic explosives and plastic material hidden on the body can be detected with a microwave noise radar system. This paper considers the basic physics of the technique and reports on the development of an initial prototype system for hand search of suspects and addresses the work carried out on optimising the Probability of Detection (PD) and False Alarm Rate (FAR).
