Title: Hybrid millimeter wave imaging system

Abstract: A hybrid mm-wave imaging system which increases the probability of detection and reduces false alarm rate. The system includes a large array of passive sensors (pixels) to provide an initial coarse picture of the environment and a small array of active sensors in the center of the large array, which is activated only when the initial passive scan detection is positive. The active array, without any mechanical scanning, illuminates the area to detect edges to provide clarity to the detected image, thereby increasing the probability of detection and reducing the false alarm rate.
