TerraSAR-X and TanDEM-X are two German Synthetic Aperture Radar (SAR) Earth observation satellites with the commercial distribution rights being owned by Airbus Defence and Space GmbH.
Their flexible acquisition modes (six different) and imaging characteristics benefit data collections from very-high-resolution (up to 0.25m) to wide-area-coverage. Due to the nature of SAR, the satellites operate independently of daylight and weather conditions resulting in an unrivalled reliability in terms of data collections.
|Archive date / refresh frequency||There are datasets available for Silicon Valley / Bay Area and New Delhi as multitemporal stacks. TerraSAR-X has got a revisit time of 11 days to the same point on Earth.|
|Resolution||Two Acquisition Modes available: 1. Staring SpotLight (ST): up to 0.25m resolution; scene size approx. 4 x 3.7km2 (); 2. StripMap (SM): up to 3m resolution; scene size 30 x 50km2. () Actual scene size depends on incidence angle|
|Processing level||SSC (Single look Slant range Complex)|
|Data format||SSC: The 32 bit file format contains both amplitude and phase information. The data is single look data.|

Multi-resolution – Multi-scale – Multi-polarized Acquisition Modes – from extensive maritime coverage to image interpretation close to optical (commercially unique resolution). Precise Monitoring System (IMINT and Mapping, Maritime Monitoring, Change Detection).
SSC is required for interferometric processing (CCD, DInSAR, PSI, SBAS etc.) and other advanced analysis methods. Precondition is specific image processing software.
