摘要

In this paper, we propose two beamforming algorithms which impose sparse constraint on beampattern to suppress the sidelobe level and enhance robustness of the beamformer against steering vector error. The sparse constraint is given by an ι_p-norm, where p ≤ 2 holds. It is shown that the proposed algorithms can be solved using iterative algorithm. Computer simulations show that the proposed algorithms not only yield lower sidelobe level than that of the conventional beamformer, but also show better robustness against steering vector error than the conventional beamformers.
