A fast nulls tracking pattern synthesis algorithm based on jammer subspace orthogonal projection is proposed, which can suppress the dynamic active jamming for LEO spaceborne array antenna. The algorithm corrects the nulls positions of radiation pattern synchronously through dynamically jammer subspace updating and iterative orthogonal projection, while the Iterative Fourier Transform (IFT) technique?is adopted to accelerate the correction. The proposed algorithm can maintain the mainlobe region and control the dynamic range ratio of excitations robustly and precisely, while minimizing the pattern sidelobe adaptively, so it is suitable for online real-time calculation in spaceborne array antenna. Simulation results verify the rapidity, effectiveness, and robustness of the proposed algorithm.
