ABSTRACT:
A method and apparatus for the resolution of targets in the presence of s distributed clutter as sea waves, rain, land, clouds and chaff. More specifically, real air targets in the proximity with this type of clutter are detected by deriving an adaptive threshold against which all radar video signals are compared. The design of the instant invention is based on a statistical knowledge of the temporal and spatial characteristics of distributed clutter so that only the magnitude of the clutter in the immediate vicinity of the target need be measured.
