Multi-frequency Polarimetric Change Analysis for Agricultural Monitoring

Inhalt:
This work analyzes the changes on the Polarimetric SAR response obtained over agricultural fields for different types of crops during its phenological evolution. A Polarimetric Change Analysis technique will be employed which is based on the optimization of the polarimetric contrast in order to extract information related to both, the intensity and the type of change. Particular attention will be given to how the phenological changes are perceived by the different frequencies, including L-, C- and X-band. For this analysis the DLR’s F-SAR CROPEX 2014 campaign will be used, containing fully polarimetric SAR data at these 3 frequencies.
