Abstract

A novel wideband millimeter-wave imaging system concept has been developed at Pacific Northwest Laboratory for the detection of concelaed weapons. Millimeter-waves are ideal for personnel surveillance applications since they will readily penetrate common clothing materials, and have relatively short wavelengths allowing for high resolution imaging. This system concept is based on a circular synthetic aperture imaging technique, in which a circular aperture is scanned and an image is formed of the target located near the scanned aperture. A laboratory imaging system has been developed and results have been obtained using both mannequins and humans with concealed weapons. The technique is readily adaptable to a real- time imaging system using a relatively small number of transceivers and a relatively slow scanner speed.
