Processing of bistatic TanDEM-X data

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
On June 21st, 2010, the German radar satellite TanDEM-X was launched and successfully placed in an orbit approaching the TerraSAR-X satellite until both systems will fly in close formation and will establish the only available bi-static interferometer in space. The primary TanDEM-X mission goal is to generate a global Digital Elevation Model (DEM) with

Accuracy assessment of the global TanDEM-X digital elevation model in a mountain environment

, 2020
The past two decades have been prolific in production of global or near-global Digital Elevation Models (DEMs) derived from satellite data. The most recent addition to the family of global DEMs is the TanDEM-X DEM with resolution of 0.4 arc sec. DEMs are

In-orbit calibration of the TanDEM-X system

2011 IEEE International Geoscience and Remote Sensing Symposium, 2011
In addition to the first satellite TSX already in-flight since 2007 [1], the second satellite TDX of the TanDEM-X system could be successfully launched in 2010 [2]. 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.

Characteristics of TanDEM-X experimental modes

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
TanDEM-X is a spaceborne mission consisting in two satellites that are operated simultaneously for bistatic SAR acquisitions. The main objective of the mission is the systematic acquisition of a global and homogeneous digital elevation model (DEM) in bistatic stripmap mode. The close formation of the satellites makes the system very flexible and allows

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.

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
