| Abstract: | The quality of data measured by microwave radiometer depends on high-accuracy on-orbit calibration.Firstly,two-point calibration scheme for conventional microwave radiometer was described.Secondly,three types of fully polarimetric calibration scheme including external calibration,internal calibration and hybrid calibration scheme were analyzed in terms of on-orbit application.Lastly,a comparative analysis of on-orbit calibration was presented between fully polarimetric and conventional radiometer in terms of calibration equation,calibration error and calibration accuracy. |
