AbstractSAR users have varying data quality requirements. It is their demands, market share, and strategic importance that ultimately dictate many fundamental engineering decisions for the design of the sensor and supporting ground segment. In this paper, we outline some considerations for the overall data quality requirements for future SAR systems, assuming that these missions will include imaging capabilities for applications with polarimetric, interferometric, and more traditional SAR modes that include single channels and/or single and multiple beams. Specifically, we draw from our experience with a number of existing SARs including ERS-1, ERS-2, J-ERS-1, and RADARSAT-1 to explore basic data quality issues that affect the geometric, radiometric, and interferometric (or phase) fidelity of products, and ultimately the reliability of the information products generated from them. These observations have implications on the design of satellite and ground segment components for future SARs such as ENVISAT and RADARSAT-2.
