Terrain scattered interference suppression for multichannel SAR

This paper proposes a novel terrain scattered interference (TSI) suppression method for multichannel SAR. This method is based on an improved Fast-time space time adaptive processing (STAP). It can be used to reject the wideband noise-like TSI signal impinging on the main beam of SAR antenna. The point-target simulation and area target simulation are used to show the working principle of the proposed algorithm and verify the proposed algorithm.
