Abstract
A passive outdoor millimeter wave illuminator for use with a concealed object detection system is disclosed. In a particular embodiment, the illuminator includes a panel having a plurality of horizontal louvers each having reflective properties for reflecting millimeter wave energy from the sky to a target and a pair of rear support arms for biasing the panel upwards. The illuminator further includes a base wherein a lower portion of the panel is rotatably mounted to a front edge of the base and the rear edge of the base is fixed to a lower end of the rear support so that the panel is capable of rotatable motion in a horizontal plane relative to the base. In addition, a slidable bushing engaged with a portion of the rear support arms is frictionally operable as to maintain the panel at the desired angle.
