Abstract
Passive millimeter wave imaging has been shown to be a useful for enhanced vision and concealed weapons detection applications. Trex Enterprises is developing a second generation passive millimeter wave imaging system which operates in real time with a 20 X 30 degree field of view and a 2K temperature sensitivity. This system is based on a pupil-plane aperture architecture used in a first generation system, but also includes advances in technology which improve system performance and utility. These include a flat panel dielectric antenna and W-band amplifiers, detectors, and processors. This second generation system will serve as the basis for a production millimeter-wave imager.Keywords
