Sensitivity of Multi-frequency Polarimetric SAR Data to Post-Fire Permafrost Changes and Recovery Processes in Arctic Tundra ...
Abstract— We used full polarimetric L-band and P-band synthetic aperture radar (SAR) data collected from the recent NASA Arctic Boreal Vulnerability Experiment (ABoVE) airborne campaign and Sentinel-1 C-band dual-polarization data to understand the sensitivity of radar backscatter intensity and phas...
