N2 - A low sidelobe level time-domain adaptive broadband beamforming is proposed in this paper by adding a sparse constraint on the output beam pattern. Then, the robustness against direction of arrival (DOA) mismatch can be achieved. The proposed method is a convex optimization problem, which can be solved by convex optimization software efficiently. Simulation and experimental results show the properties of sidelobe suppression and robustness against DOA mismatch by comparing with the worst-case performance optimization (RB-RI-WC) algorithm.
