A novel robust STAP beamforming algorithm

The purpose of this paper is to improve the performance of the traditional optimum space-time adaptive processing (STAP). The signal model and the basic idea of the STAP are given, and then a robust STAP algorithm is propounded. In this algorithm, a linear estimation is used to estimate the direction of arrival. Theoretical analysis and simulation results show that the Robust STAP can improve the SINR and robustness of the algorithm.
