Using the RADARSAT SAR versatility to enhance Fine Resolution imaging capabilities

The RADARSAT SAR design includes a number of selectable and programmable features to provide the wide range of operational imaging modes, ranging from ScanSAR to Fine Resolution. The potential range of imaging capabilities which this versatile instrument could provide is significantly larger than is currently offered operationally, and additional modes are progressively being introduced to meet identified demand. This paper considers the fine resolution imaging capabilities, describing some additional options which are now available and suggesting further modes, with wider access and even finer resolution, which the instrument could provide in the future.
