| Abstract: | Radiometric calibration is the basis for quantitative application of remote sensing.First the concept,significance and method of radiometric calibration are explained.Then the calibration methods of pre-launch calibration,on-board calibration and vicarious calibration are introduced,and the role of these calibration methods at different stages are analyzed.Taking the focus on the field calibration,scene calibration and cross calibration of vicarious calibration method,the basic principles,scope and current research status of these calibration methods are expatiated.Finally,the prospects of international radiometric calibration are summarized and the proposals for domestic radiometric calibration are put forward,which will enable the users to obtain the more accurate remote sensing data. |
| Keywords: | radiance calibration vicarious calibration test site calibration sense calibration cross calibration |
