| Abstract: | On the basis of introducing briefly the periodic calibration of spaceborne microwave radiometer (SMR), the antenna pattern correction of the external periodic calibration is discrited and its brightness temperature and errors are analysed. The brightness temperature of "cold"'"hot" calibration loads is also caculated. Finally, the method of improvingSMR calibration accuracy is given. |
