摘要：
Due to the high speed and critical height, clutter spectrum of hyper sonic airborne radar turn out to be seriously non-stationary. The multiple clutter aliasing which resulted from range ambiguity and Doppler ambiguity are analyzed in this paper. For solving the problem that the homogenous samples are starving, a knowledge-aided space time adaptive processing method is proposed in which samples are replenished through the high fidelity clutter simulation based on prior information such as digital elevation map and the usage of history data. The simulation results illustrate that the proposed method greatly improves the performance of clutter suppression for the hyper sonic airborne radar.
