TerraSAR-X / TanDEM-X
TerraSAR-X and TanDEM-X dependably acquire high-resolution and wide-area radar images independent of the weather conditions. The two satellites feature a unique geometric accuracy that is unmatched by any other spaceborne sensor.
Both satellites are almost identical and operate in six alternate operating modes for a wide range of applications in Earth observation: Ranging from Staring SpotLight mode with a resolution of up to 25 cm at a scene size of e.g. ~ 4 km x 3.7 km mainly for image intelligence applications to Wide ScanSAR providing a resolution of 40 m at a scene size of 270 km × 200 km (extendable to a scene length of 1,500 km) particularly suitable for maritime applications. Other applications include highly precise change detection and monitoring applications, support of intelligence and security mission, disaster response and as well as mapping and generation of digital elevation models using interferometry and radargrammetry. Thanks to different polarimetric combinations (single or dual polarisation and even full Polarimetric) and processing levels the delivered imagery can be tailored specifically to meet the requirements of the application.

Spare a thought this Christmas for researchers hunkered down on their Polarstern icebreaker, adrift in the frozen Arctic Ocean. Subjected to temperatures as low as -45°C and the perpetual darkness of the polar winter, they are willing participants in MOSAiC – the world's largest and longest polar research expedition. Despite the darkness, however, the researchers and crew remain aware of what is happening close by. How? With the help of radar imaging satellites.
ESA are pleased to announce the release of PolSARpro v6.0 (Biomass Edition) software, which is the latest version of the ESA PolSARpro Toolbox (Polarimetric SAR data Processing and Educational Toolbox).
