Multi-baseline Pol-InSAR Forest Height Estimation in the pres- ence of temporal decorrleation
Polarimetric Synthetic Aperture Radar (SAR) Interferometry (Pol-InSAR) is a radar remote sensing technique, based on the coherent combination of radar polarimetry (Pol-SAR) and SAR interferometry (InSAR) which is substantially more sensitive to structural parameters of forest volume scatterers (e.g. forest) than conventional interferometry or polarimetry alone. However, temporal decorrelation i...
متن کاملALOS−PalSAR Pol−InSAR Data Analysis: First Results
This paper presents a first calibration and quality analysis of Pol−InSAR data acquired by the ALOS−PalSAR based on deterministic and extended scatterers. The calibration of Pol−InSAR data requires the estimation and compensation of polarimeteric and interferometric system and propagation (through the ionosphere and atmosphere) induced distortions. Constant phase errors/offsets appear in the po...
متن کاملMultibaseline Polarimetric Sar Interferometry Forest Height Inversion Approaches
Polarimetric SAR interferometry (Pol-InSAR) is a radar remote sensing technique that is sensitive to the vertical distribution of scattering processes in volumes. The Random Volume over Ground (RVoG) model is a powerful tool used to invert forest height from PolInSAR data. But Pol-InSAR inversion performance depends critically on uncompensated decorrelation contributions (i.e. temporal decorrel...
متن کاملThe Impact of Temporal Decorrelation over Forest Terrain in Polarimetric SAR Interferometry
While polarimetric SAR interferometry (Pol-InSAR) techniques are today well established, a critical issue in the case of repeat-pass spaceborne measurements is temporal decorrelation, caused by changes within the scene occurring in the time between the acquisitions. Indeed, temporal decorrelation has been identified as the most critical factor for a successful implementation of Pol-InSAR parame...
متن کاملSpaceborne Polarimetric SAR Interferometry: Performance Analysis and Mission Concepts
We investigate multichannel imaging radar systems employing coherent combinations of polarimetry and interferometry (PolInSAR). Such systems are well suited for the extraction of bioand geophysical parameters by evaluating the combined scattering from surfaces and volumes. This combination leads to several important differences between the design of Pol-InSAR sensors and conventional single pol...
