Forest 3D Radar Reflectivity Reconstruction at X-Band Using a Lidar Derived Polarimetric Coherence Tomography Basis Open
Tomographic Synthetic Aperture Radar (SAR) allows the reconstruction of the 3D radar reflectivity of forests from a large(r) number of multi-angular acquisitions. However, in most practical implementations it suffers from limited vertical …

Calibration and Validation Activities in the Context of the 2023 GABONX Airborne SAR Campaign for Tropical Forest Height and Change Analysis over Gabon Open
Tropical forests are of great ecological and climatological importance. Although they only cover about 6% of Earth’s surface, they are home to approx. 50% of the world’s animal and plant species. Their trees store 50% more carb…

Large-Scale Forest Height Mapping by Combining TanDEM-X and GEDI Data Open
The present study addresses the development, implementation, and validation of a forest height mapping scheme based on the combination of TanDEM-X interferometric coherence and GEDI waveform measurements. The very general case where only a…

Forest Height Estimation by Means of TanDEM-X InSAR and Waveform Lidar Data Open
Model-based forest height inversion from Pol-InSAR data relies on the realistic parameterization of the underlying (vertical) radar reflectivity function. In the context of interferometric TanDEM-X measurements – especially in the global s…

A Comparison of Function Bases For Polarization Coherence Tomography in Forest Scenarios Open
Polarization Coherence Tomography addresses the TomoSAR inversion by approximating the vertical reflectivity profile by a weighting functions of a basis. The individual weights can be estimated from the available interferometric coherences…
