摘要
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.
A new beamformer is ppesented in this paper,which utilizes the eigenstructure of the correlation matrix to enhance the performance of the linearly constrained minimum variance(LCMV)beamformer.The advan tages of the beamformer are that it can eliminate the sigmal cancellation when a desired signal is contained in the correlation matrix,and has good beam pateern with low sidelobe level and fast convergence properties,which are confirmd by computer simulation.
