Abstract

Abstract

In practical application, the adaptive weight of the sidelobe canceller can not be updated frequently. Thus, the spatial nonstationary interference would lead to the mismatch between the weight and the snapshots, which seriously deteriorates the cancellation performance of the sidelobe canceller. A null broadening algorithm is proposed for the sidelobe canceller, which is performed by tapering the conventional beamformer output and the covariance matrix of the auxiliary elements simultaneously. The taper vector and matrix only depend on the elements location and null width meaning that they can be designed offline and are quite suitable for practical use. Simulation results verify the effectiveness of the proposed method.
