TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) is successfully operating now already since 2010 and has opened a new era in spaceborne radar remote sensing. A single-pass SAR-interferometer with adjustable baselines in across- and in along-track directions is formed by adding a second (TDX), almost identical spacecraft to TerraSAR-X (TSX) and flying the two satellites in a closely controlled formation.

The generation of a global TanDEM-X Digital Elevation Model (DEM) as the primary mission goal has been successfully succeeded with an unprecedented accuracy. Beyond the TanDEM-X DEM applications based on cross-track as well as along-tack interferometry have been provided a considerable importance. For super test sites regular and continuous data stacks have been acquired since the beginning of the mission and data were provided to the scientist allowing analysis of geophysical parameters in space and time.

The lecture will provide a short mission status overview and is mainly focusing on applications that deliver 4D information content.

SPEAKER’S BIO:

Irena Hajnsek (AM’ 01, M’06, SM’09, FM’14) is since November 2009 Professor of Earth Observation at the Swiss Federal Institute of Technology (ETH) Zürich Institute of Environmental Engineering and at the same time head of the Polarimetric SAR Interferometry research group at the German Aerospace Center Microwaves and Radar Institute. Her main research interests are in electromagnetic propagation and scattering theory, radar polarimetry, SAR and interferometric SAR data processing techniques, environmental parameter modelling and estimation. She received her Dipl. degree (Honors) in 1996 from the Free University of Berlin, Germany and the Dr. degree (Honors) in 2001 from the Friedrich Schiller University of Jena, Germany. Since 2010 she is the science coordinator of the German satellite mission TanDEM-X and proposed satellite mission Tandem-L. She was Technical Program Co-chair of the IEEE IGARSS 2012 Symposium in Munich. Since 2013 she is a member of the IEEE GRSS AdCom and since 2016 she is the vice president of the IEEE GRSS Technical Committees.
