ABSTRACT:
The invention provides an infra-red target detection system in which an array of infra-red detectors is scanned vertically in swathes and horizontal scanning is effected by sampling the output of each detector in turn. Addresses of target detections in the vertical and horizontal are stored and read out into an X and Y co-ordinate target position store if a detection resulting from scanning in the vertical corresponds to a detection resulting from scanning in the horizontal.
