Interferometric processing of TanDEM-X data

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
Since July 2010, TerraSAR-X and TanDEM-X jointly acquire interferometric data. Starting their common commissioning phase with a so called pursuit monostatic configuration with 3 seconds time lag between the two passes, they were later put in a close formation in October 2010, acting since then as the first freely configurable bistatic SAR ...

The bistatic aspect of the TanDEM-X mission

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
In addition to the promising and well known features in the field of monostatic interferometry and polarimetry, TanDEM-X can also be used for bistatic purposes. In this Helix orbit concept one TerraSAR-X satellite (TSX) serves as transmitter whereas the reflected signal is received by the transmitter as well as by an almost identical satellite (TDX ...

Navigation and control of the TanDEM-X formation

The Journal of the Astronautical Sciences, 2008
Germany is presently preparing the first operational formation flying mission for Synthetic Aperture Radar (SAR) interferometry in low-Earth orbit. TanDEM-X comprises two nearly identical satellites (TSX and TDX) that are launched with a two-year time shift in 2007 and 2009, respectively.

Distributed imaging with TerraSAR-X and TanDEM-X

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
This paper reports on several experiments performed with the TerraSAR-X (TSX) and the TanDEM-X (TDX) satellites. The experiments consist in the generation of improved image products by coherently combining the images acquired individually by both satellites, hence the name distributed imaging.

Bistatic synchronization and processing of TanDEM-X data

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
The German TanDEM-X mission flies the two satellites TerraSAR-X (TSX) and TanDEM-X (TDX) in a close orbit formation establishing a bistatic interferometer in space. A major challenge in bistatic SAR data processing is the synchronization of the satellites' oscillators.

Tests of the TanDEM-X DEM calibration performance

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The TanDEM-X mission based on two satellites provides a radar interferometer in space with the goal to derive a global Digital Elevation Model (DEM) with never achieved quality for a global coverage: a global DEM with a relative height accuracy of 2m and 10m absolute.

Monostatic calibration of both TanDEM-X satellites

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
The primary object of the TanDEM-X mission is to generate a highly accurate digital elevation model (DEM) with never achieved accuracy on global scale [1]. But in addition to this bistatic TanDEM-X mission the monostatic TerraSAR-X mission have to be operated in parallel with both satellites. Consequently the second satellite TDX, successfully launched

InSAR and DEM quality monitoring of TanDEM-X

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
TanDEM-X is an interferometric SAR (InSAR) mission acquiring bistatic images with two satellites. Systematic mapping of the Earth's land masses will provide individual interferometric data sets which will be mosaicked and calibrated into a global Digital Elevation Model (DEM).

TanDEM-X for Cryosphere Applications

2020
<p>In this presentation the focus is laid on cryospheric applications served by the single-pass interferometer TanDEM-X. The German Radar mission TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) is already successfully in operation since 2010 and is delivering continuously data over the Earth surfaces.</p&
