A Novel Adaptive Pattern Control Method Based on LCMV
基于LCMV线性约束的自适应方向图控制

This paper describes a simple adaptive pattern control method based on Linearly Constrained Minimum Variance (LCMV). The quiescent pattern weights are imposed in constrain which make the overall beamformer sidelobe response equal the desired quiescent response and form nulls in the direction of interference at the same time. The sidelobe exhibits large ripples in condition of small training sample size and the diagonal loading method is combined with this method, which improve the convergence speed in sidelobe. The effectiveness of this new method is illustrated by a few designed examples.
