借助于先进的激光测量技术．可对天线近场测量系统的定位误差进行精确测量并加以校正。基于对扫描架机械误差源的分析，本文叙述了线性激光测量方法，介绍了激光跟踪系统的应用原理及前景，提出了利用激光测量数据进行定位误差校正的基本思路。

The positioning error of the antenna near field measurement system can be exactly measured and corrected by using the advanced laser measurement technology. Based on the analysis of machinery errors of the scanner, this paper presents the linear laser measurement method. And then, the principle and applying prospect of the laser tracking system are introduced. Finally it gives the main idea of positioning error correction relied on the laser measurement data.
