| 摘 要： | 为了研究大口径反射镜紧缩场系统中板间缝隙对静区特性的影响，先采用空域法进行分析，根据空域仿真结果选择合适的拼接方式，并以此方式再进行时域和角域仿真.时域和角域中可做到主波与干扰波的分离，比较不同观察点的时域图和不同观察平面的角域图中的干扰波，最后得到较理想的静区范围.这种分析方法对于分析大型紧缩场中板间缝隙对静区特性的影响是有效的.

| Abstract: | In order to study the impact of the the panel gap on quiet zone characteristics in the large com-pact antenna test range ( CATR) systems, spatial domain method is adopted firstly, and an appropriate means of joining together is chosen according to the spatial simulation results, in this way, time and an-gular domain results are simulated then. Time and angular domain simulation can separate interference wave from main wave, comparing the interference wave of different points in the time and angular domain the reasonable range of ideal quiet zone can be obtained. This kind of analysis is efficient for analyzing the impact of the panel gap on quiet zone characteristics in the large CATR. |
