| This paper comprises two parts: radar clutter simulation and adaptive moving target indication.In the former part, we analyse the generation mechanism of single-channel radar correlated clutter and illuminate the simulated modeling way of Rayleigh, Log-norm, Wei bull, K-distributed clutter with special power spetrum. All these models are used into the practical simulation of ground clutter, cloud-rain clutter and chaff jammer according to their features. Klemm model is discussd specially for multi-channel airborne phased array radars. The model is tested by practical data.In the latter part, we discuss some classical algorithms of conventional AMTI and STAP and present a new method to combine space conventional beamformer with the maximum improve factor AMTI filter. Then we present a concrete method of putting DPCA into aerial phased array's AMTI, Simulation result proves the validity. The method has great value to practice project. |
