CALIBRATION SYSTEM FOR MMW RADIOMERER
毫米波辐射计定标系统

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.
