Journal ArticleDOI
A tutorial on synthetic aperture radar
Alberto Moreira,Pau Prats-Iraola,Marwan Younis,Gerhard Krieger,Irena Hajnsek,Konstantinos Papathanassiou +5 more
TL;DR: This paper provides first a tutorial about the SAR principles and theory, followed by an overview of established techniques like polarimetry, interferometry and differential interferometric as well as of emerging techniques (e.g., polarimetric SARinterferometry, tomography and holographic tomography).
Journal ArticleDOI
TanDEM-X: A Satellite Formation for High-Resolution SAR Interferometry
Gerhard Krieger,Alberto Moreira,Hauke Fiedler,Irena Hajnsek,Marian Werner,Marwan Younis,Manfred Zink +6 more
TL;DR: A detailed overview of the TanDEM-X mission concept is given which is based on the systematic combination of several innovative technologies, including a novel satellite formation flying concept allowing for the collection of bistatic data with short along-track baselines, as well as the use of new interferometric modes for system verification and DEM calibration.
Journal ArticleDOI
First demonstration of airborne SAR tomography using multibaseline L-band data
Andreas Reigber,Alberto Moreira +1 more
TL;DR: The authors present the concept of aperture synthesis for tomographic imaging for the case of a multibaseline imaging geometry and propose a method for reduction of the height ambiguities associated to the irregular and undersampled spatial distribution of the imaging positions.

Journal ArticleDOI
Unambiguous SAR signal reconstruction from nonuniform displaced phase center sampling
TL;DR: This letter derives an innovative reconstruction algorithm and shows that an unambiguous reconstruction of a SAR signal is possible for nonuniform sampling of the synthetic aperture.
