Abstract :
The sensor calibration accuracy is an important indicator of SAR satellite system´s performance and data quality. Towards geometric and radiometric calibration of Radarsat- 2 satellite (RS2), this paper researched the procedure and key techniques of space-borne SAR field calibration, including corner reflectors´ (CRs) design, CRs´ arrangement in the field, acquirement of CRs´ peak RCS value and the surveying scheme. Besides, RS2´s calibration accuracy was validated, giving reference for its quantitative application.
