Measurements of Forest Biomass Change Using L-band Sar Backscatter
Three-year forest above-ground biomass change is to be measured using L-band synthetic aperture radar (SAR) backscatter. Measurements are also made using P-band backscatter for comparison. The radar data were collected in the airborne BioSAR 2007 and BioSAR 2010 campaigns over the hemiboreal Remningstorp test site in southern Sweden. Regression models for biomass will be developed using referen...
متن کاملSar Tomography at L Band Applied to Forest Structure Analysis
The upcoming launch, scheduled for the next decade, of the BIOMASS and the TANDEM L space missions will have a special focus on forest applications. However, it is still necessary to research the amount and the quality of information relevant to forest structure parameters that those SAR sensors can possibly retrieve. SAR tomography is an advanced technique capable to measure the three dimensio...
متن کاملModeling L-band radar backscatter of Alaskan boreal forest
Synthetic aperture radar (SAR) data were acquired over Bonanza Creek Experimental Forest (Alaska) in March 1988 under thawed and frozen conditions. For h e stands analyzed, Cband backscatter at 4 2 O 4 5 " lacidence angle was 2.7-6.9 dB smaller under frozen than under thawed conditions for white spruce and balsam poplar, with the largest difference at HV and the smallest at EM polarization. The...
متن کاملAssessment of stand-wise stem volume retrieval in boreal forest from JERS-1 L-band SAR backscatter
JERS-1 L-band SAR backscatter from test sites in Sweden, Finland and Siberia has been investigated to determine the accuracy level achievable in the boreal zone for stand-wise forest stem volume retrieval using a model-based approach. The extensive ground-data and SAR imagery datasets available allowed analysis of the backscatter temporal dynamics. In dense forests the backscatter primarily dep...
متن کاملMonitoring of Forest Structure Dynamics by Means of L-Band SAR Tomography
Synthetic Aperture Radar Tomography (TomoSAR) allows the reconstruction of the 3D reflectivity of natural volume scatterers such as forests, thus providing an opportunity to infer structure information in 3D. In this paper, the potential of TomoSAR data at L-band to monitor temporal variations of forest structure is addressed using simulated and experimental datasets. First, 3D reflectivity pro...
