Abstract
A radar system that enhances the display of moving targets by using negative scan-to-scan correlation to determine which pixels will be displayed at the brightest level. More specifically, a bit image stores a multi-bit scan-to-scan correlated history for each pixel on a display screen, and when new video data is received on a scan, the bit image memory is modified in accordance therewith. A pixel is enhanced to the brightest level only if a return is received from a spacial location from which returns were not received on previous scans. Thus, a target that moves to a new location is displayed at the brightest level because it doesn't correlate with returns from prior scans.
