Abstract

Abstract

When the conventional virtual array is used for adaptive beamforming, the performance is largely influenced with the transforming area, even the serious distortion of the whole beam map will be aroused if an improper transforming area is chosen. This paper expressed an improvement solution based on subspace processing. With the presented algorithm, the interference null can be steadily formed. Meanwhile, it is not sensitive to which transforming area is chosen. On the other hand, this method can still form a good beam although there are a few snaps. Numerical examples attest the correctness and the validity of the proposed algorithm.
