Research on Simulation Method of Radar Clutter Suppression for Large Scale Air Defense and Antimissile Simulation System

When simulating the large scale air defense and antimissile system, the subsystem simulation must have the qualifications of both good effect and high efficiency. To meet the needs, this paper studied on the simulation method of the clutter suppression for the ground based radar in the large system particularly. It proposed building the database of the clutter suppression ratio through abundant simulations beforehand, and then acquiring the clutter suppression ratio by looking up the table or interpolation when simulating the large system. The affection the clutter does to radar detection is analyzed at first. Then the clutter modeling method and clutter suppression modeling method are studied. Next this paper gives the rules of the clutter suppression performance of MTI vary with the related factors by simulation. Finally it introduces the concrete method of building the clutter suppression performance database of MTI under a fixed circumstance. The proposed simulation method has both good effect and high efficiency which can be used in the large scale air defense and antimissile simulation system.
