Crop Growth Assessment Using Sentinel-1 GRD SAR Descriptors

This study analyses the recently proposed dual polarimetric descriptors (viz., the pseudo scattering entropy Hc, the co-pol purity parameter mc, and the pseudo scattering-type parameter θc) from GRD SAR data for crop growth assessment. The analysis of these descriptors is carried out over a time series of Sentinel-1 data for a winter crop (wheat) and a summer crop (potato) at a test site in Germany. The algorithm is implemented on the Google Earth Engine (GEE) cloud platform for Sentinel-1 SAR data.
