Quantization Effects in TanDEM-X Data [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2015
TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) is an innovative space-borne bistatic synthetic aperture radar (SAR) system comprising the twin satellites TerraSAR-X and TanDEM-X. The primary objective of the mission is the generation of a worldwide, timely, and consistent digital elevation model (DEM) in bistatic SAR configuration with

THE GLOBAL TANDEM-X DEM: PRODUCTION STATUS AND FIRST VALIDATION RESULTS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
The TanDEM-X mission will derive a global digital elevation model (DEM) with satellite SAR interferometry. Two radar satellites (TerraSAR-X and TanDEM-X) will map the Earth in a resolution and accuracy with an absolute height error of 10m and a relative ...

TanDEM-X: 10 Years of Formation Flying Bistatic SAR Interferometry

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
On June 21, 2010, the TanDEM-X mission was launched and opened a new era in spaceborne radar remote sensing. The first formation flying radar system was built by extending the TerraSAR-X synthetic aperture radar (SAR) mission by a second, TerraSAR-X-like

Beyond the 12m TanDEM-X DEM [PDF]

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
The standard TanDEM-X product meats HRTI-3 DEM specification and comes with a sample spacing of 12 m.We apply non-local means (NL) interferogram filtering to the TanDEM-X data. In this paper, we present modifications of the original NL filter which render it more appropriate and efficient for massive processing of TanDEM-X data.
