Mission
To foster high-quality synthetic aperture radar imagery from airborne and spaceborne systems through precision calibration in radiometry, phase, and geometry, and validation of higher level products
Terms of Reference
The objectives of the Synthetic Aperture Radar subgroup, beyond those of the WGCV, are to:
- Act as a forum for international technical interchange on the evolving methodologies, techniques, and equipment of SAR calibration and validation
- Determine standard definitions and calibration-validation requirements for synthetic aperture radar imaging systems
- Support changes in CEOS formats and user products as appropriate
- Facilitate international cooperative programs in the calibration and validation of SAR systems
- Educate the SAR community
Action Plan
The major activity of the SAR subgroup in recent years has centred on the annual meetings. This is expected to continue. In the 2002 meeting, it was agreed to set up calibration and validation reference sites (to include both natural and man made targets) for the purposes of providing an easily accessible source of reference calibration data to data providers, showing the mutual compatibility between different SAR systems, and demonstrating the total quantitative and qualitative quality of SAR data. The 2003 meeting of the SAR subgroup should focus on the problem of full polarimetric SAR calibration, both establishing requirements and techniques.
