Abstract
Traditional beamforming algorithms are hard to be applied to distributed arrays which have special array structures. An improved virtual beamforming algorithm based on non-uniform sparse optimization of multiple transform regions is proposed in this paper. Through this algorithm, adaptive beamforming for distributed arrays could be obtained while the main lobe position is not shifted and the nulls are deepened.
