【Abstract】 This paper introduces a clutter tracking technique used for airborne PD radar.Combining the clutter feature of airborne PD radar and characteristic of local entropy algorithm,we apply this algorithm to the clutter tracking.We propose the judging criteria of similarity to maximum local entropy that is used to segment the simulated data after local entropy filter.The hybrid filter,which is composed of K nn filter and local entropy filter,has been used to get clutter edge detection.This scheme has been verified to be successful in several typical experiments.更多还原
