ABSTRACT:
A method for operating a target tracker and processing the image data received from its sensor to select the target from the clutter and to select an aimpoint on the target of particular utility. The method processes the gaps between image segments on a given horizontal scan line. The processing proceeds from left to right across the scanned scene. Hence when a gap is located which has its center located to the right of the center of the image scene, the image segment to the left of the gap is the segment closest to the horizontal center of that line of data. Sucessive lines of data are processed to locate the centermost target segment. If such successive target segments are contiguous they are combined and processed as a target to determine an aimpoint which is the median of the target. Operating according to this method the tracker will select those contiguous image segments which are located closest to the center of the image scene and will select the target median as the aimpoint on the target.
