Cascaded multi-baseline interferometry with bistatic TerraSAR-X/TanDEM-X observations for DEM generation

, 2021
As the spaceborne mission dedicated to bistatic SAR interferometry (InSAR), the TerraSAR-X/TanDEM-X satellite constellation can acquire highly coherent data pairs with flexible baseline configurations and minimal atmospheric disturbances, which are well ...

TanDEM-X Long-Term System Performance After 10 Years of Operation

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
The TanDEM-X mission, formed by the TanDEM-X satellite in cooperation with its almost identical twin TerraSAR-X (TSX), has mainly been designed to acquire bistatic synthetic aperture radar (SAR) images of the Earth. Initiated in 2010, the primary mission

Interferometric processing algorithms of TanDEM-X data [PDF]

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
The purpose of this paper is to provide an algorithmic overview of the interferometric processing embedded in the Integrated TanDEM-X Processor (ITP), settled to the generation of the raw digital elevation model (DEM). The main processing blocks are described, with a focus on the spectral matching of the azimuth spectra, the high-precision ...

First Bistatic Spaceborne SAR Experiments with TanDEM-X [PDF]

, 2011
TanDEM-X is a high-resolution interferometric mission with the main goal of providing a global and unprecedentedly accurate digital elevation model (DEM) of the Earth surface by means of single-pass X-band SAR interferometry.

Improving Forest Height-To-Biomass Allometry With Structure Information: A Tandem-X Study

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Allometric relations that link forest above ground biomass to top forest (i.e., canopy) height are of particular significance in the context of lidar and interferometric synthetic aperture radar remote sensing, as both techniques allow accurate height ...

Processing system and algorithms for the TanDEM-X mission [PDF]

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
In 2009, the German radar satellite TerraSAR-X will be supplemented with the TanDEM-X satellite to form the first bi-static single pass interferometer in space. TanDEM-X will fly close to TerraSAR-X in a controlled helix configuration for 3 years to jointly acquire interferometric SAR data in bistatic mode.

Mapping the landscape of tandem repeat variability by targeted long read single molecule sequencing in familial X-linked intellectual disability

BMC Medical Genomics, 2018
Background The etiology of more than half of all patients with X-linked intellectual disability remains elusive, despite array-based comparative genomic hybridization, whole exome or genome sequencing.
