Hand-Held Microwave Search Detector

This paper describes the development of a patented, novel, low cost, microwave search detector using noise radar technology operating in the 27-40 GHz range of frequencies, initially reported in SPIE 2004. Experiments have shown that plastic explosives, ceramics and plastic material hidden on the body can be detected with the 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. The radar uses a novel lens system and the design and modelling of this for optimum depth of field of focus will be reported
