S-1 based crop analyses

Processing pipelines for the calculation of backscatter intensity, polarimetric decomposition parameters and coherence values are presented. Analyses regarding the informative value of these SAR features are exemplified by analysing timeseries for a few hundred fields. Correlations to the phenological development of the crops are made and random forest-based classifications are performed.
