Research on the Method of Reducing the Receiver Non-linear Deviation of the Microwave Radiation Imager

Chen Weiying;Liu Gaofeng;He Jiakai;Pan Li;Shanghai Aerospace Electronic Technology Institute;  
FY-3 Microwave Radiation imager,which is used for atmosphere remote sensing,ocean remote sensing and earth remote sensing,is one of the important means of monitoring meteorology,ocean and other disaster.Whether the Microwave Radiation imager can obtain the valuable exploration data,and get quantitative application and real business use or not when it is running in orbit,it mainly depends on the precision of the calibration.The size of the receiver non-linear deviation has the direct relationship with calibration accuracy,the factors affecting the non-linear deviation and the methods of reducing non-linear deviation are analyzed in this paper,the receiver non-linear deviation of the Microwave Radiation imager under vacuum condition is provided finally.
