Paper Abstract

A SAR-GMTI algorithm based on space-time adaptive processing (STAP) in frequency domain by multi-channel SAR is proposed. The paper deduces the theoretical formula of the clutter suppression in-depth based on frequency STAP and finds that the output is a chirp signal and similar to the input signal of the moving targets before suppressed, so FrFT is chosen to detect them and estimate their moving parameters. The analyses in theory and simulator results show that our new algorithm is effective.
