摘要： 提出了一种改进的数字式波束形成的快速自适应算法,即具有严格约束最小功率的抽样矩阵梯度算法(CSMG)。它综合了传统抽样矩阵梯度、算法和具有严格约束的最小功率自适应算法的优点。计算机模拟表明,此算法波束方向随约束角度而变,自适应调零能力较强,收敛速度也较快。

Abstract: This paper provides an improved fast adaptive algorithm for digital beamforming. It is an algorithm with strictly constrained minimum power sampling matrix gradient (CSMG). It has merits of both traditional sampling matrix gradient (SMG) and strictly constrained minimum power adaptive algorithm. The outputs of computer simulation are given. The result indicates that direction of beam will change as constraint angle changes. It can adaptively adjust zero very well. The algorithm are fast convergent.
