Summary: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.
