摘　　要：针对频率选择表面(Frequency Selective Surface,FSS)天线罩高温热匹配试验不允许涂黑和粘贴热电偶的技术需求,并考虑到结构表面高反射率的特点,通过设计辐射加热器并采用调试反控技术方案,建立了接触式与非接触式测温数据间的定量关系,实现了天线罩表面非接触式温度的准确测试和控制,以及对天线罩结构的有效辐射热匹配试验考核。本文研究工作可以为相关材料和结构的辐射加热试验和测试研究提供参考。Aiming at the technical requirements that the high-temperature thermal matching test of radome with frequency selective surface(FSS)does not allow blackening and pasting thermocouples,and considering the characteristics of high reflectivity on the structure surface,by designing the radiation heater and adopting the technical solutions of debugging and inverse control,the quantitative relation between contact and non-contact temperature measurements is established,and the accurate non-contact measurement and control of temperature on the radome surface and the effective radiation thermal matching test of radome structure are achieved.The present work can provide reference for the study on radiation thermal test and measurement of related materials and structures.
