天线平面近场测量中一种近远场变换方法研究

内容简介：本文研究了一种应用于天线平面近场测量中完成近远场变换的数值算法。利用此方法可以依据天线平面近场测试数据快速简便地求得天线远场方向图及其它特性，其精度较高；同时可以很方便地进行探头修正，并讨论天线平面近场测试中各关键参数对测试结果的影响。本文给出了理论依据和具体计算实例，与传统方法进行了比较，并得出了结论。

Abstract：This paper provided a new algorithm used in antenna's planar near-field measurements to conduct near-field and far-field transformations.The far-field patterns and performances of antenna under measurement can be obtained rapidly and efficiently by this method compared to some conventional methods,the precision is good enough.At the same time,the corrections of probe-effect can be easily done and the effect of some key parameters in measurements can be easily discussed.This paper gives principles and calculation examples,and conclusions are reached.
