Video-rate millimeter-wave camera for concealed weapons detection

W-band radiometers have been shown to be effective in detecting metallic and non-metallic weapons concealed under heavy garments in both indoor and outdoor situations. With a real time-time MMW camera, we now may display subjects with weapons in both indoor and outdoor situations. The system consists of a linear array of W-band detectors in a 12 inch Cassegrain system with a mechanical scanner along with support and display hardware.
