摘要
本文介绍了一种通过构造增广数据矩阵并对其进行奇异值分解的修正 MVDR 波束形成器.在快拍次数有限时,该方法能提高零点的精度和加深零点的深度,使干扰更加有效地得到抑制.文中详细给出了这种方法的工作原理并从理论上分析了其可行性,最后用计算机仿真实验验证了这种方法的有效性.
This paper introduces a modified MVDR beamformer based on constructing augmented data matrix and its singular value decomposition. In the scenario of limited snapshot number,this method can make the null positions more accurate and the nulls more deep, so as to cancel the interference more effectively .The operation principles of this method are described in detail,and its feasibility is also analyzed theoretically. Finally,some simulation results to verify its effectiveness are presented.
