A null broadening beamforming method of virtual antenna array
Wenxing Li, Yu Zhao · 2016
A null broadening beamforming method of virtual antenna array is proposed, by which the real antenna array is transformed into virtual antenna array and the component of interference power in the covariance matrix is increased. Compared with the approach of covariance matrix taper, the null depth of the proposed method is improved. The validity of the proposed method is verified by theoretical analysis and simulation results.
