TanDEM-X: First Scientific Experiments during the Commissioning Phase

Inhalt:
In this paper new and innovative techniques during the commissioning phase of TanDEM-X will be presented that are firstly demonstrated on a satellite platform. The focus is on the secondary goals of TanDEM-X that are assigned for the third year of the mission time life due to the tight schedule for the acquisition of the highly accurate global digital elevation model. Therefore, a variety of scientific experiments are planned to be performed already during the commissioning phase. The first experiments are related to bistatic processing, Polarimetric SAR Interferometry, double differential SAR Interferometry, decorrelation measurements, supperresolution and velocity measurements. The data quality and the results obtained will be validated and are discussed.
