A Clutter Spectrum Compensation Method for Non Side-Looking Airborne Radar with Range Ambiguity
摘要
Abstract
The ground clutter of the non side-looking airborne radar (non-SLAR) is range-dependent, which makes the ground clutter Doppler distribution widen in the space-tune domain. When the range ambiguity is considered,the short and far slant range clutters are mixed. Although the existing range-dependence compensation methods can mitigate the range-dependence of the short slant range clutter, they change the space-time distribution of the far slant range clutter. It severely decreases the performance of the space-time adaptive processing (STAP) . We propose a range ambiguity clutter compensation method which adds the constraint protection of the far slant range clutter based on the registration-based method (RBC) .When the proposed method is applied to the range ambiguity clutter, it can not only mitigate the range dependence of the short slant range clutter, but also keep the distribution of the far slant range clutter unchanged. Moreover, the proposed method can achieve good performance when the antenna error exists in the clutter data. The computer simulation results show the validity of the proposed method.关键词
