Analysis of Clutter Suppression Capability in Surface Movement Radar

Surface movement radar(SMR)is used to monitor aircraft and vehicles on the airport surface and other objects on runway.As primary radar,SMR can receive the echoes from other unrelated objects,such as the surface reflection of runways,taxiways,aprons,meadows and the echoes of rain,fog and haze on transmission path.How to detect and track useful target within these useless background echoes is an important issue for SMR.In this paper,based on the basic function of SMR,the major clutter and assessment methods for SMR has been discussed and the methods of clutter suppression has been presented correspondingly.
