Technical Note / Note technique The RADARSAT-2 SAR processor

The RADARSAT-2 synthetic aperture radar (SAR) processor processes RADARSAT-2 signal data into georeferenced and geocoded imagery. The processor is a subsystem of the RADARSAT-2 ground segment and is referred to as the processing and distribution subsystem (PDS). This paper provides an overview of the PDS, including descriptions of the system context, system heritage, functionality, architecture, and processing algorithms. The output product format is also summarized.
