Robust adaptive beamforming algorithm for suppressing fast-moving broadband jamming

A robust space-time adaptive processing algorithm for suppressing fast-moving broadband jamming was proposed. The proposed method modified the covariance matrix of wideband jamming based on the analysis of the model of wideband signal and the rotation of the space-time steering vector. Combined with the diagonal loading technique, the broadening nulling algorithm can effectively suppress interference, which increases the robustness of the algorithm. The performance analysis of computer simulation verifies the efficiency of the proposed algorithm.
