一、前言 随着航天技术的发展,对飞行器天线罩(窗)的抗热性、电性能的稳定性提出了越来越高的要求,这就出现了在模拟气动加热条件下电介质电性能测量技术。在过去工作的基础上,我们研制了微波电介质高温自动测量仪,主要用于对石英、陶瓷、微晶玻璃、玻璃钢等介质材料的介电常数与温度关系的连续测量,为天线罩、热天线的电气设计提供数据。
I. INTRODUCTION With the development of aerospace technology, higher and higher requirements are put forward on the heat resistance and the stability of the electrical performance of the aircraft radome (window), and this presents the measurement of the electrical properties of the dielectric under simulated aerodynamic heating conditions technology. Based on the past work, we have developed a microwave dielectric high temperature automatic measuring instrument, which is mainly used for the continuous measurement of the dielectric constant and temperature of dielectric materials such as quartz, ceramics, glass ceramics, glass fiber reinforced plastic and so on. The electrical design provides the data.
