Progress in Standardization of Calibration and Validation of SAR.

Synthetic aperture radar (SAR) is widely used in many applications due to its all weather and all day observation capabilities. With the development of many spaceborne and airborne SAR systems, the amount of SAR data and products is increasing rapidly. Meanwhile, how to ensure the quality of data and products becomes more important. Calibration and validation are the essential processes to improve and evaluate the quality of the data and products. Standardization of SAR calibration and validation is a critical step towards higher product quality and better comparability and interoperability. This paper presents recent efforts and future work of SAR calibration and validation of ISO/TC 211.
