Toeplitz化在ESB自适应波束形成算法中的应用

把Ｔｏｅｐｌｉｔｚ化和基于特征空间（ＥＳＢ）自适波速形成算法相结合，针对等距线提出了一种新的波束形成算法并进行了理论分析，该算法通过对估计得到的阵列信号相关矩阵进行Ｔｏｅｐｌｉｔｚ化，减小有限次采样引起的误差，获得较快的收敛速度，并能有效克服ＥＳＢ算法不能在相干环境下工作的缺点，计算机仿真结果证实了这种算法的有效性。

Application of the Toeplitz technique to ESB adaptive beamforming

By combining the Toeplitz technique and the Eigenspace Based Algorithm for adaptive beamforming, this paper presents a novel beamforming algorithm for the uniform linear array and analyzes the algorithm. The algorithm reduces the sample errors by using the Toeplitz technique for the sample correlation matrix, so that it can rapidly converge and efficiently overcome the problem that the ESB Algorithm can not work in the environment of coherent signals. computer simulation results show that the method is effective.
