ABSTRACT:
An electrooptic support measure comprised of black hole radiometer within a orward looking infrared (FLIR) scanning imaging video processing system to provide friendly military personnel with the capability of surveying terrain to determine if enemy thermal imaging devices (TIDs), which have cryogenic temperature detectors therein, are being used in surveillance against the friendly military personnel. The lens and scanners of the FLIR scanning imaging video processing system have wide field of view (FOV) for search operation, and each of the plurality of the IR detectors that form an IR detector array operate as a plurality of radiometers having narrow (FOVs) when the black hole radiometer capability circuit of this disclosure is being used. The black hole radiometer (BHR) mode may be selectively activated in the FLIR scanning imaging video processing system by manual operation of a selector switch, or the FLIR and BHR modes may be automatically sequenced to a preprogrammed schedule in a logic circuit wherein the BHR mode may be switched in on say every second or fifth video channel to provide continual switching back and forth between the FLIR and BHR modes at an image display.
