Abstract

A clutter suppressor/target locator apparatus is configured to manipulate rget video data on a particular channel according to a predetermined algorithm, so as to selectively emphasize those area of a scene containing targets of appreciable contrast to the background and de-emphasize those areas where the brightness levels change gradually from point to point. The algorithm takes into account points ahead and behind the point or picture element being tested, and also equal points or adjacent channels. The apparatus is substantially free of false alarms, and the unique configuration thereof allows detection of the presence of a target on an extremely rapid basis.
