基于相关矩阵的特征分解，本文提出了一种改进的线性约束最小方差波束形成（LCMV）新算法，当目标信号含于相关矩阵中时，新算法能有效地抑制信号对消现象，并且具有良好的波束保形能力和快速收敛特点，计算机仿真结果验证了这些优点．
Based on the eigendecomposition of correlation matrix, an improved LCMV algorithm is proposed in this paper. When the target signal is contained in the correlation matrix, the new algorithm can effectively suppress the signal cancellation and has a good performance Beamforming capability and fast convergence characteristics, computer simulation results verify these advantages.
