| 摘 要： | 研究的是单约束最小无失真响应（MVDR）波束形成问题,在基于共轭梯度法（CG）的多级嵌套维纳滤波（MSNWF）基础上,提出了一种简化的单约束波束形成方法.该方法与原有的一般旁瓣对消器（GSC）波束形成方法相比,无需计算约束矢量的正交补,节省了计算量.文章还给出了两种方法的等价性证明.仿真结果表明新方法可行、有效.

| Abstract: | The task for MVDR beam-forming was discussed.Based on the CG-based MSNWF,a simplified single constrained beam-forming was proposed.Comparing with the generalized side-lobe canceller (GSC),the new approach saves the consumption of computation for the orthogonal component of the steering vector.The equivalence between the GSC and the proposed approach is also proved.Simulation result shows that the new implementation is feasible and efficient. |
