Abstract
As a result of its relatively short wavelength coupled with relatively high penetration of many materials, millimeter- wave imaging provides a powerful tool for the detection of concealed articles. By using a passive approach such as that implemented here, it is possible to image (detect) concealed weapons and articles or look through certain types of walls, all without generating any form of radiation that might raise health concerns. In this paper we show the results of two years of upgrades to our imager that have resulted in true 30 Hz imaging and 5 Kelvin instantaneous thermal sensitivity. High resolution ground based video and image data taken at distances from 12 to over 66 feet together with airborne flight test data will be presented as representing state-of-the-art in passive millimeter-wave imaging.
