| 摘 要： | 文章以一个小型吸波箱为研究对象,采用TD软件对吸波箱的温度与其内部放置的天线表面热流均匀性之间的关系进行了仿真分析,依据仿真结果设计吸波箱的控温回路和控温策略,最后通过模拟试验对吸波箱的控温效果进行验证。试验证明通过对吸波箱进行合理控温能够将天线表面热流的不均匀度控制在5%以内。

| Abstract: | This paper studies a small microwave absorbing box, using the TD software to simulate the temperature of the box and the heat flux uniformity of the antenna, and based on the results of the simulation, the temperature control circuit and strategy are designed. The temperature control capability of the box is validated through the simulation test which shows that by controlling the temperature of the microwave absorbing box reasonably, the heat flux uniformity can be kept within 5%. |

| Keywords: | vacuum thermal test microwave absorbing box temperature-control temperature uniformity |
