摘要：
The generalized eigenspace-based beamformer (GEIB) has demonstrated more robust capabilities than the linearly constrained minimum variance beamformer and the eigenspace-based beamformer. However, it still couldn't deal with large pointing errors near the mainlobe edge. To cure the problem, the paper presents a modified algorithm, which obtains the weight vector by firstly calibrating the presumed steering vector with a rotated vector, and then utilizing the calibrated steering vector for the GEIB. Several computer simulations are provided for illustrating the advantages of the proposed algorithm over the GEIB.
