Influence of sar antenna on radarsat image quality

The RADARSAT mission utilizes a Synthetic Aperture Radar (SAR) system to produce images representing terrain radiometric backscatter levels. The SAR system consists of Space and Ground Segments. The Space Segment is a polar orbiting satellite at 800 km nominal altitude carrying a C-band (5.3 GHz) radar sensor. The Ground Segment provides the SAR image data processing facility, as well as the associated data reception and satellite control and telemetry facilities.
