| 摘 要： | 介绍了在微波暗室里进行天线精度测量的基本原理，从结构受最大载荷变形后对天线测试台精度的影响这一角度出发，给出了结构参数和变形与整体刚度之间的关系。同时对结构刚度进行详细分析，提出以系统重量最低和比刚度最高的加权因子法的多目标优化函数及优化策略，最后，在研究与分析的基础上，对高精度天线测试台结构特点进行了总结。

| Abstract: | It is very important that antenna target support structure and rigidity during antenna precision measurement in microwave darkroom. Based on the precision effect and requirement, when structure suffered to maximum load, relationship of parameter between structure and distortion was provided.Besides, structure distortion analysis was carried out in detail.In addition, target rigidity/weight ratio and total mass minimizing method were put forward. |
