The Target Screener/FLIR System and its performance are discussed in this paper. The Autoscreener (Augmented Target Screener Subsystem, ATSS*) was designed and built by Honeywell for the Air Force in 1974. This system operated on imagery data from an AAS-27 sensor. detected man-made objects (MMOs), and cued the operator by displaying a symbol at each sector area containing MMOs. It achieved 92 percent probability of detection of MMOs and less than 3 percent probability of false alarm. The Autoscreener was modified to accept FUR imagery and its feasibility in detecting MMOs and cueing the FLIR operator was evaluated. The Autoscreener/FLIR system performance was evaluated. The system achieved 95 percent probability of detection with 5 percent probability of false alarm.
