Abstract:Due to the earth’s rotation or non-sidelooking radar configuration, the spectrum of Space Based Radar (SBR) clutter varies with the range and shows non-stability. The non-stability of clutter will degrade Space Time Adaptive Processing (STAP) performance significantly and should be compensated. A new spectrum registration based method is proposed which uses non-uniformed discrete frequency sampling points. The mathematical model of the non-uniformed spectrum registration method is built. The choices of these non-uniformed discrete frequency samples and the estimate of clutter covariance matrix after compensation are also studied. Simulations show that the proposed spectrum registration method can compensate the non-stability effectively and achieve approximately optimal performance.
