| 摘 要： | 本文基于天线平面近场测量技术的基本理论,利用解析法和数值分析法研究分析了天线平面近场测量中有限扫描面截断误差对天线远场特性结果的影响,给出了有限扫描面截断误差所带来的天线辐射方向性图的误差的数量级,即天线方向性图的不确定度,为天线近场测量技术的误差补偿提供了一定的理论依据,同时也得到了一些对实际测量有一定指导意义的结论.

| Abstract: | This paper is based on the basic theory of antenna planar near-field measurement technology to study the limited scanning plane truncation error and its effect on the antenna radiated pattern by making use of the numerical method. Through comparing with the theoretic result, the up limit or uncertainty of the antenna radiated pattern is given. This provides some theoretic proofs for the error compensation of the antenna near-field measurement technology, and at the same time, some directive conclusions are drown for the practical measurement. |
