为了弥补阵列天线导向矢量失配对测向性能的影响，提出基于稳健Capon波束形成技术的矢量相关测向方法。与直接使用相位差的常规相关干涉测向技术不同，该方法首先利用稳健Capon波束形成技术估计目标信号的真实导向矢量；然后通过导向矢量的相关拟合确定目标信号方向。通过仿真分析，得出了以测向为衡量标准时不确定集约束参数的选择原则。仿真结果表明该方法能够弥补阵列流型失配的影响、准确测量目标信号方向。

In order to compensate the influence of the array antenna steering vector mismatch,the vector correlation direc-tion finding method based on the robust Capon beamforming technology is proposed. Different from the conventionnal correlation interference direction finding technology using the phase difference,the new method uses robust Capon beamforming technology to estimate the true steering vector of the target signal,and then determe the direction of the target signal by the steering vector correlation fitting. The selection principle of uncertain constraint parameter was obtained through simulation analysis. The simula-tion results shows that the method can compensate the impact of the steering vector mismatch,and measure the target signal di-rection accurately.
