| 摘 要： | 提出了一种计算自适应方向图权向量的迭代算法。为满足迭代矩阵的收敛条件，算法根据协方差矩阵的最大Gemchgorin半径选择对角加栽值对协方差矩阵进行对角加栽；通过对协方差矩阵进行简单的矩阵分裂；进而给出自适应权向量的迭代解形式。仿真表明，所提出的算法能在快拍数较少时形成稳健的特性良好的方向图。

| Abstract: | In this paper, an iterative algorithm is presented to compute weight vector of adaptive pattern. Firstly, to satisfy the convergence condition of iterative matrix, the algorithm applies diagonal loading technology to the covariance matrix and the diagonal loading value is given based on maximal gerschgorin radius of the covariance matrix. The iterative solution of adaptive weight vector is given by using simple matrix split for the covariance matrix. Simulations show the algorithm can form robust and better pattern with few snapshots. |
