Combined Radar-Radiometer Surface Soil Moisture and Roughness Estimation

A robust physics-based combined active-passive (C-AP), or active-passive, surface soil moisture and roughness estimation methodology is presented. Soil moisture and roughness retrieval is performed via optimization, i.e., minimization, of a joint objective function, which constrains similar resoluti...
