Agricultural Monitoring Using Polarimetric Decomposition Parameters of Sentinel-1 Data

The performance of single regression models is compared to those of multiple regression models, including backscatter coefficients in VV and VH polarisation as well as polarimetric decomposition parameters entropy and alpha. Characteristic temporal profiles of entropy, anisotropy, and alpha reflecting the main phenological changes in plants as well as the meteorological differences between the two years are observed for both crop types.
