基于改进型点匹配技术的阵列误差校正方法

MPMT-based approach for array calibration

针对阵元间互耦往往会导致智能天线总体性能急剧下降这一现象,提出了一种快速有效的校正方法。该方法以实测的阵元方向图为基础,通过改进型点匹配技术和求最优解来对误差矩阵进行精确的估计。

In accordance with the phenomena that array mutual coupling always degrades the performance of smart antenna system severely, the paper presented a fast and effective calibration approach to solve the problem. The main ideal of this new method was accurate estimation of the error matrix, which was based on measured element patterns, modified point matching technology and calculation for optimal solution. The reliability of the method is testified by computer simulation results with array pattern synthesis.
