  • Application of SAR time-series and deep learning for estimating landslide occurence time 
    Wang, W.; Motagh, M.; Plank, S.; Orynbaikyzy, A.; Roessner, S. (Katlenburg-Lindau : Copernicus Publications, 2022)
    The time series of normalized difference vegetation index (NDVI) and interferometric coherence extracted from optical and Synthetic Aperture Radar (SAR) images, respectively, have strong responses to sudden landslide ...
  • Development of large area covering height model 
    Jacobsen, Karsten (Göttingen : Copernicus GmbH, 2014)
    Height information is a basic part of topographic mapping. Only in special areas frequent update of height models is required, usually the update cycle is quite lower as for horizontal map information. Some height models ...
  • Implementing Synthetic Aperture Radar Backprojection in Chisel – A Field Report 
    Rother, Niklas; Fahnemann, Christian; Blume, Holger (New York, NY : Springer, 2022)
    Chisel is an emerging hardware description language which is especially popular in the RISC-V community. In this report, we evaluate its application in the field of general digital hardware design. A dedicated hardware ...
  • Iterative Verfahren zur Detektion und Rekonstruktion von Gebäuden in SAR- und InSAR-Daten 
    Sörgel, Uwe (Hannover : Universität, 2003)
    [no abstract]
  • Matching persistent scatterers to buildings 
    Schunert, A.; Schack, L.; Sörgel, Uwe (Göttingen : Copernicus GmbH, 2012)
    Persistent Scatterer Interferometry (PSI) is by now a mature technique for the estimation of surface deformation in urban areas. In contrast to the classical interferometry a stack of interferograms is used to minimize the ...
  • Optimized Minimum-Search for SAR Backprojection Autofocus on GPUs Using CUDA 
    Rother, Niklas; Fahnemann, Christian; Wittler, Jan; Blume, Holger (Piscataway, NJ : IEEE, 2020)
    Autofocus techniques for synthetic aperture radar (SAR) can improve the image quality substantially. Their high computational complexity imposes a challenge when employing them in runtime-critical implementations. This ...
  • Persistent scatterer aided facade lattice extraction in single airborne optical oblique images 
    Schack, Lukas; Sörgel, Uwe; Heipke, Christian (Göttingen : Copernicus GmbH, 2015)
    We present a new method to extract patterns of regular facade structures from single optical oblique images. To overcome the missing three-dimensional information we incorporate structural information derived from Persistent ...
  • Quality assessment of high resolution radar DSMs 
    Sefercik, Umut G.; Jacobsen, Karsten (Göttingen : Copernicus GmbH, 2010)
    Radar remote sensing has a significant role in remote sensing technologies and develops rapidly. A series of new synthetic aperture radar (SAR) satellites has been launched to space having various operation modes which ...
  • Simulation assisted high-resolution psi analysis 
    Schunert, Alexander; Balz, T.; Liu, K.; Liao, M.S.; Sörgel, Uwe; Wegner, Jan Dirk (Göttingen : Copernicus GmbH, 2010)
    Since the first demonstration of the potential of the differential SAR interferometry in the early 1990s a lot of effort has been made to accurately estimate ground deformation with imaging radar sensors. This led to the ...
  • Synthetic Aperture Radar Algorithms on Transport Triggered Architecture Processors using OpenCL 
    Rother, Niklas; Mätzner, Leonard; Jääskeläinen, Pekka; Leppänen, Topi; Schleusner, Jens; Blume, Holger (Piscataway, NJ : IEEE, 2024)
    Live SAR imaging from small UAVs is an emerging field. On-board processing of the radar data requires high-performance and energy-efficient platforms. One candidate for this are Transport Triggered Architecture (TTA) ...
  • TanDEM-X mission: Overview and evaluation of intermediate results 
    Sörgel, Uwe; Jacobsen, Karsten; Schack, Lukas (Göttingen : Copernicus GmbH, 2013)
    The German Aerospace Center (DLR, Deutsches Zentrum für Luft- und Raumfahrt) currently conducts the bistatic interferometric synthetic aperture radar (SAR) Mission TanDEM-X, which shall result in a DEM of global coverage ...
  • Time domain based image generation for synthetic aperture radar on field programmable gate arrays 
    Cholewa, Fabian (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2019)
    Aerial images are important in different scenarios including surface cartography, surveillance, disaster control, height map generation, etc. Synthetic Aperture Radar (SAR) is one way to generate these images even through ...
  • Totalsynthese von Rickiol E3 und Synthese von Chlorotonil A-Derivaten 
    Böhm, Andreas (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)
    Der erste Teil der vorliegenden Arbeit befasst sich mit der Totalsynthese des 2017 von Stadler et al. isolierten makrolidischen Naturstoffes Rickiol E3. Den entscheidenden Schritt zum Aufbau der wichtigen 1,3,5-Triol-Einheit ...
  • Using lattice topology information to investigate persistent scatterers at facades in urban areas 
    Schack, Lukas; Sörgel, Uwe (Göttingen : Copernicus GmbH, 2013)
    Modern spaceborne SAR sensors like TerraS AR-X offer ground resolution of up to one meter in range and azimuth direction. Buildings, roads, bridges, and other man-made structures appear in such data often as regular patterns ...
