Tandem-X Dem Change Maps Stacks: Towards Tandem-X 4D
IGARSS 2023 - 2023 IEEE International Geoscience and Remote Sensing Symposium, 2023 The TanDEM-X mission acquires data used for the generation of Digital Elevation Models (DEMs) since 2010. From this data two global DEMs are already generated or in generation. The DEM acquisitions used for new TanDEM-X DEM 2020 are also used to generate

SAR Tomography at the Limit: Building Height Reconstruction Using Only 3-5 TanDEM-X Bistatic Interferograms [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2020 Multi-baseline interferometric synthetic aperture radar (InSAR) techniques are effective approaches for retrieving the 3-D information of urban areas. In order to obtain a plausible reconstruction, it is necessary to use more than twenty interferograms.

Evaluation of TanDEM-X DEMs on selected Brazilian sites: comparison with SRTM, ASTER GDEM and ALOS AW3D30 [PDF]
Remote Sensing of Environment 212C (2018) pp. 121-133, 2017 A first assessment of the TanDEM-X DEMs over Brazilian territory is presented through a comparison with SRTM, ASTER GDEM and ALOS AW3D30 DEMs in seven study areas with distinct geomorphological contexts, vegetation coverage and land use. Visual analysis and elevation histograms point to a finer effective spatial resolution of TanDEM-X compared to SRTM ...

Quantization Effects in TanDEM-X Data [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2014 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

A Nonlocal InSAR Filter for High-Resolution DEM Generation from TanDEM-X Interferograms [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2018 This paper presents a nonlocal InSAR filter with the goal of generating digital elevation models of higher resolution and accuracy from bistatic TanDEM-X strip map interferograms than with the processing chain used in production. The currently employed boxcar multilooking filter naturally decreases the resolution and has inherent limitations on what ...

Deep Learning Solutions for TanDEM-X-based Forest Classification [PDF]
arXiv, 2019 In the last few years, deep learning (DL) has been successfully and massively employed in computer vision for discriminative tasks, such as image classification or object detection. This kind of problems are core to many remote sensing (RS) applications as well, though with domain-specific peculiarities.

On the Derivation of Volume Decorrelation From TanDEM-X Bistatic Coherence
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2022 The bistatic interferometric coherence is affected by different sources of error, among which volume decorrelation, which quantifies the amount of noise caused by volume scattering mechanisms.
