Comparison of topography- and aperture-dependent motion compensation algorithms for airborne SAR
Prats Iraola, Pau; Câmara de Macedo, Karlus A.; Reigber, Andreas; Scheiber, Rolf; Mallorquí Franquet, Jordi Joan (IEEE, 2007-07-31)
Article
Accés obertThis letter presents a comparison between three Fourier-based motion compensation (MoCo) algorithms for airborne synthetic aperture radar (SAR) systems. These algorithms circumvent the limitations of conventional MoCo, ... -
Estimation of Azimuth Phase Undulations with Multisquint Processing in Airborne Interferometric SAR Images
Prats Iraola, Pau; Mallorquí Franquet, Jordi Joan (2003-06-30)
Article
Accés obertThis letter presents a technique to detect and correct phase errors appearing in interferometric airborne synthetic aperture radar (SAR) systems due to the lack of precision in the navigation system. The technique is ... -
Interpolation-free Coregistration and Phase-Correction of Airborne SAR Interferograms
Prats Iraola, Pau; Reigber, Andreas; Mallorquí Franquet, Jordi Joan (IEEE, 2004-07-31)
Article
Accés obertThis letter discusses the detection and correction of residual motion errors that appear in airborne synthetic aperture radar (SAR) interferograms due to the lack of precision in the navigation system. As it is shown, ... -
Refined estimation of time-varying baseline errors in airborne SAR interferometry
Reigber, Andreas; Prats Iraola, Pau; Mallorquí Franquet, Jordi Joan (IEEE, 2006-01-31)
Article
Accés obertThe processing of airborne synthetic aperture radar (SAR) data requires a precise compensation of the deviations of the platform movement from a straight line. This is usually carried out by recording the trajectory with ... -
Topography dependent motion compensation for repeat-pass interferometric SAR systems
Prats Iraola, Pau; Reigber, Andreas; Mallorquí Franquet, Jordi Joan (IEEE, 2005-04-30)
Article
Accés obertThis letter presents a new motion compensation algorithm to process airborne interferometric repeat-pass synthetic aperture radar (SAR) data. It accommodates topography variations during SAR data processing, using an ... -
Validation of SAR interferometric phase corrections in the squinted case for DEM quality enhancement
Bara Iniesta, Marc Antoni; Prats Iraola, Pau; Mallorquí Franquet, Jordi Joan; López, J. (2002-10)
Article
Accés obertThe focus of this report is synthetic aperturc radar (SAR) interferoinctric techniques for mapping applications, in the presencc of possible high squint values. Theoretical and expcrimental analysis show the presence ...
