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

Elevation changes of the Holm Land Ice Cap, northeast Greenland, from 1978 to 2012–2015, derived from high-resolution digital elevation models

Arctic, Antarctic, and Alpine Research, 2018
Greenland’s peripheral glaciers and ice caps are key indicators of climate change in the Arctic, but quantitative observational data of their recent evolution are sparse.

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.

Paddy-Rice Monitoring Using TanDEM-X [PDF]

IEEE Transactions on Geoscience and Remote Sensing, 2015
This paper evaluates the potential of spaceborne bistatic interferometric SAR images for the monitoring of biophysical variables in wetlands, with a special interest on paddy rice. The assessment is made during the rice cultivation period, from transplanting to harvesting time (May to October) for fields around Gala lake (Turkey), one of the largest ...
