TerraSAR-X and TanDEM-X
TerraSAR-X TanDEM-XThe TerraSAR-X and TanDEM-X missions are realised in
the frame of a Public Private Partnership (PPP) between
the German Ministry of Education and Science (BMBF)
represented through the German Aerospace Centre (DLR)
and Airbus Defence and Space. DLR is also responsible for
instrument calibration, operation and scientific use of data.
The TanDEM-X (TerraSAR-X add on for Digital
Elevation Measurement) is commercial German
(SAR) Earth observation satellite for generating a
global (DEM) with an extremely high accuracy
corresponding to HRTI (High Resolution Terrain
Information) - Level 3 specifications.
The TerraSAR-X (Terrain Synthetic Aperture
Radar) is commercial German (SAR) Earth
observation satellite operating in X-Band radar
Senser with a range of different operation,
allowing it to acquire image with different
swath width, resolutions and polarisation.

1.Bistatic Mode
Both satellite look into a common footprints
2. Pursuit Monostatic Mode
Both satellite operated independently with
time difference
3. Alternating bistatic Mode
Transmitted form any one satellite and recoded
on both simultaneously
Observational
Modes
Independent of weather conditions
Unique agility (Rapid switches between
imaging modes and polarizations)
Spotlight mode provides to assess man made
objects more precisely
