Abstract

The TerraSAR-X project is a public private partnership between Astrium GmbH and the German Space Center DLR. Astrium will launch the satellite in late 2005 and holds the rights of commercial data exploitation. DLR is curently developing the ground segment and is responsible for the scientific expoitation of the data.

Even if the mission goal is not primarily SAR interferometry, TerraSAR-X offers a number of new perspectives to SAR interferometry when compared to ERS and also ENVISAT:

- High resolution of 3 meters and better in stripmap and spotlight mode.

- The option for a burst synchronized ScanSAR mode - The high range bandwidth will allow large baselines and the option for highly precise DEM generation. - X-Band will show new scattering properties - High observation frequency due to short repeat cycle and variable incidence angles - An along track interferometric mode.

The available products relevant for interferometry are presented and other relevant topics like orbit control and phase stabilization are discussed.
