Errata: Digital Beamforming on Receive: Techniques and Optimization Strategies for High-Resolution Wide-Swath SAR Imaging (2009, background): “In addition, one has to account for the azimuth loss factor Laz that considers the decay of the joint Tx/Rx azimuth pattern which attenuates the recorded signal while the added noise power remains spectrally white [45].”
Evaluation of TanDEM-X DEMs on selected Brazilian sites: Comparison with SRTM, ASTER GDEM and ALOS AW3D30 (2017, methodology): “…Measurements) goal was to produce a Global DEM with 12 m spatial resolution, from radar interferometry (InSAR) with two satellites (TerraSAR-X and TanDEM-X) in a controlled orbit with a baseline of 250-500 m (Krieger et al., 2007; Martone et al., 2012; Gruber et al., 2016; Rizzoli et al., 2017).”
HRSID: A High-Resolution SAR Images Dataset for Ship Detection and Instance Segmentation (2020, methodology): “The original SAR imageries for constructing HRSID are 99 Sentinel-1B imageries, 36 TerraSAR-X and 1 TanDEM-X [49] imageries; the resolution of SAR imageries is under 3m to keep detailed and accurately represented feature of ships.”

A tutorial on synthetic aperture radar (2013, methodology): “To illustrate this problem, we consider a spaceborne radar interferometer like TanDEM-X [76], which operates in the interferometric imaging mode with a nominal bandwidth of B 100MHz. r = Choosing a baseline which is just % 10 of the critical baseline, the corresponding height of ambiguity is about…”
GEDI launches a new era of biomass inference from space (2022, methodology): “For example, GHMB has been used with GEDI and wall-to-wall imagery from TanDEM-X [54], which provides interferometric synthetic aperture radar (SAR) from two orbiting satellites, to produce both height and biomass estimates for areas where no GEDI data exist, and at finer spatial resolutions than 1 ”
Accuracy assessment of the global TanDEM-X Digital Elevation Model with GPS data (2018, methodology): “The standard deviation of the interferometric phase ru is strongly related to geometrical considerations, the number of looks and the measured coherence (Krieger et al., 2007; Gonzalez and Bräutigam, 2015).”
Tandem-L: A Highly Innovative Bistatic SAR Mission for Global Observation of Dynamic Processes on the Earth's Surface (2015, methodology): “Boreal forests at higher latitudes can moreover be imaged in the alternating bistatic mode which doubles the phase to height scaling, thereby increasing the effective baseline by a factor of two [33].”
MIMO-SAR: Opportunities and Pitfalls (2014, methodology): “TanDEM-X which can be regarded as a MIMO-SAR with two transmit and two receive channels that provide together three virtual phase centers [34].”
