摘　　要：根据微波谐振腔的谐振频率随充入介质不同而变化的原理,研制出了一种能够精确测量大气折射率的微波折射率仪。实验证实,该微波折射率仪的测量精度远远高于常用五九型探空仪和轻型电容式折射率仪,且具有反应速度快、精度高、体积小、重量轻等特点。该仪器不仅可实用于高精度雷达电波折射误差修正,也可实用于大气波导的精确测量和大气精细结构的精确测量等方面。Based on the principle of the resonance frequency of microwave resonant cavity which changes with different medium entering, a microwave refractometer was created that could accurately measure the atmospheric refractivity. The experiment shows that the microwave refractometer is better than 59 radiosonde and capacitive refractometer in measuring accuracy, and that is has the merits of high reaction speed, high measuring accuracy, small bulk and so on. This equipment can not only be used for the accuracy correction of radar radio wave refraction error, but also for the accurate measurement of atmospheric duct and fine structure.
