摘要

阵列互耦、幅相误差以及阵元位置误差的综合影响会严重影响阵列天线的测向性能．针对均匀圆阵，该文基于特征空间类方法给出了一种新的阵列误差有源校正算法．新算法是以交替迭代的方式给出，其目标函数建立在子空间基本原理的基础上，并且适用于多个校正源同时存在的情况．文中还给出了阵列误差参数估计唯一性的必要条件，仿真实验验证了新算法的有效性．

Abstract

The combined effects of mutual coupling

gain-phase errors and sensor position errors of an array degrade severely its performance of the direction finding. Aimed at the uniform circular array(UCA)

a novel active calibration algorithm for array errors is presented based on the eigenstructure method. The algorithm is given in alternative iterative style

and its target function is built on the properties of signal subspace. It is suitable for the situation when the calibration sources exist at the same time. The necessary condition for uniqueness of the parameter estimation is also given in this paper. The simulation experiments show the effectiveness of the novel algorithm.
