Geolocation and Stereo Height estimation Using TerraSAR-X Spotlight Image Data
(2011)
We have studied the geographic position of several high-resolution spotlight TSX images by investigating the location of deployed radar corner reflectors. Results show that the geolocation accuracy is better than the ...
High resolution spaceborne INSAR simulation with extended scenes
(2005)
The Inverse–EETF4 (Extended Exact Transfer Function 4th order) is used to simulate
raw data and a complete INSAR processing chain for high squint has been developed.
Phase differences for a spaceborne INSAR geometry are ...
Spaceborne Bistatic SAR Processing Using the EETF4 Algorithm
(2009)
In this letter, the fourth-order extended exact transfer function (EETF4) is adapted for spaceborne bistatic synthetic aperture radar (SAR) processing. The problems with high squint and large bistatic Doppler centroid ...
ERS tandem InSAR processing for DEM generation, glacier motion estimation and coherence analysis on Svalbard
(2003)
This paper describes the unique InSAR (Interferometric Synthetic Aperture Radar) processing algorithms at Norwegian Defence Research Establishment (FFI) and how ERS (European Remote Sensing Satellite) tandem data are used ...
High-resolution Spaceborne SAR Processing Using the Decomposed Transfer Function
(2017)
In this paper a new analytic decomposed transfer function (DTF) for spaceborne SAR (Synthetic Aperture Radar) processing is calculated using the stationary phase approximation and Taylor’s series expansion. The DTF copes ...
Using stereo SAR and InSAR by combining the COSMO-SkyMed and the TanDEM-X mission satellites for estimation of absolute height
(2013)
The objective of this work is to estimate absolute height in synthetic aperture radar (SAR) interferograms. Since height in interferograms is relative, we use stereo SAR with several satellites to achieve absolute height ...
Change Detection Using Time and Look Angle Series of Geocoded TanDEM-X Staring Spotlight Images
(2021-03-26)
This article describes the analysis of changes in time and look angle series of TanDEM-X (TDX) and TerraSAR-X (TSX) staring spotlight images over the regions around Kjeller near Oslo in Norway and the town Nikel in Russia ...
Using the Pauli Scattering Mechanisms for Analysis of Polarimetric SAR Images from RADARSAT Constellation and TanDEM-X Missions
(2022-07-13)
This article describes techniques for extraction of information in polarimetric images from RADARSAT constellation mission (RCM) and TanDEM-X (TDX) and TerraSAR-X (TSX) satellites. Using the boundary conditions of Maxwell's ...
Combination of stereo SAR and InSAR for DEM generation using TanDEM-X spotlight data
(2017)
The objective of this work is to generate accurate digital elevation models (DEMs) from synthetic aperture radar (SAR) interferograms using the spotlight and staring spotlight modes during the TanDEM-X (TDX) science phase. ...
