Tropical-Forest-Parameter Estimation by Means of Pol-InSAR: The INDREX-II Campaign [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2009
This paper addresses the potential and limitations of polarimetric synthetic aperture radar (SAR) interferometry (Pol-InSAR) inversion techniques for quantitative forest-parameter estimation in tropical forests by making use of the unique data set acquired in the frame of the second Indonesian Airborne Radar Experiment (INDREX-II) campaign - including ...

TanDEM-X Pol-InSAR Inversion for Mangrove Canopy Height Estimation

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2015
This paper presents mangrove canopy height estimations using single- and dual-pol TanDEM-X (TDX) data by means of Pol-InSAR techniques. Using the TDX data for forest applications, the penetration capability of X-band into the volume and the polarimetric diversity of interferometric coherence can create false effects that could sometimes lead to biased ...

Antarctic snow-covered sea ice topography derivation from TanDEM-X using polarimetric SAR interferometry [PDF]

open access: yesThe Cryosphere, 2021
Single-pass interferometric synthetic aperture radar (InSAR) enables the possibility for sea ice topographic retrieval despite the inherent dynamics of sea ice. InSAR digital elevation models (DEMs) are measuring the radar scattering center height.

Pol-Insar Forest Height Inversion Using Tomosar Reflectivity Profiles [PDF]

open access: yes2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
The realistic parameterization of the underlying (vertical) radar reflectivity profile is critical for a model-based inversion of forest height from polarimetric interferometric (Pol-InSAR) data. Indeed, an appropriate parameterization not only affects the final estimation performance, but also enables the inversion from a reduced observation space in ...

EVALUATION OF AIRBORNE L- BAND MULTI-BASELINE POL-INSAR FOR DEM EXTRACTION BENEATH FOREST CANOPY [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
DEM beneath forest canopy is difficult to extract with optical stereo pairs, InSAR and Pol-InSAR techniques. Tomographic SAR (TomoSAR) based on different penetration and view angles could reflect vertical structure and ground structure.

LabSAR, a one-GCP coregistration tool for SAR–InSAR local analysis in high-mountain regions

open access: yesFrontiers in Remote Sensing, 2022
The coregistration of single-look complex (SLC) SAR images for InSAR or offset tracking applications is often performed by using an accurate DEM and precise orbital information. However, in cold regions, such DEMs are rare over high-latitude areas or not
