چکیده
In this Paper the potential of multi-temporal PolSARdata for soil surface roughness estimation is investigated. The study utilizes microwave backscatter collected from the Demmin test-site in the North-East Germany during the whole agri-phenological cycle in 2006 using quad-pol L-Band SLC E-SAR data. For ground truthing soil surface roughness were measured using photogrammetric imaging techniques. The correlation between several ground truth roughness inidces and three well established polarimetric roughness estimators showed only good results for Re[RRLL]. Final results in form of multi-temporal roughness maps showed only satisfying results due to the fact that the presence and development of particular plants affected the derivation.
