In order to effectively improve the robustness against the direction error of arrival and the polarization parameter error, this paper addresses a spatial-polarization domain joint-robust adaptive beamforming algorithm.First of all, the Interference-Plus-Noise Covariance Matrix (IPNCM) is reconstructed on the direction-polarization angle interval of each interference signal.Then, the steering vector of the desired signal is estimated on its direction-polarization angle interval.The joint-robust beamforming weighting is designed based on the reconstructed IPNCM and the estimated steering vector for airspace-polarization domain.The simulation results show that the proposed algorithm is robust against the steering vector mismatch caused by the direction error of arrival and the polarization parameter error.
