摘要
研制了的小口径天线毫米波辐射计自然变温智能定标系统 ,该系统实现了所有数据的自动采集与分析 .利用该系统对 8mm狄克式辐射计进行了定标实验 ,得到了该辐射计的主要性能和定标方程 .对其进行的精度分析表明该定标系统的天线温度不确定度为 1.0 5 82K .
An intelligent calibration system with temperature of blackbody naturally varying used for small antenna MMW radiometer was developed. All data acquirsition and analysis were automatically realized. The system was applied to calibrate a Dick 8mm radiometer. Main performances and calibration equation of the radiometed were obtained. The precision analysis shows that the calibration uncertainty of antenna temperature is about 1.0582K.
