Space-time Two-dimensional Clutter Modeling and Peformance Analysis of STAP for Space-based Radar

A space-time two-dimensional modeling method of clutter for space-based radar based on a geometric model of movement is presented in this paper.The effects of the earth's rotation and the clutter's range Doppler ambiguity have been considered in the model,which is helpful to overcome the defect that the traditional one-dimensional modeling method is hard to describe clutter's two-dimensional characteristics.Meanwhile,the modeling has a low computation and is suitable for clutter's quick simulation with a wi...
