SCoBi – Physics-based Modeling & Simulation
Polarimetric Effects– Fully polarimetric
– Any combination of linear/circular polarization
Configuration Effects
– Altitude
– Spreading loss over vegetation depth
Antenna Effects– Cross-polarization
coupling– Beam divergence– Polarization mixing– Orientation– Beamwidth– Sidelobes
Virtual Vegetation
– Mix vegetation– Growing vegetation– Seasonal effects
InterferometricEffects
– Complex Voltage– Orientation– Beamforming
ignals of Opportunity herent static Scattering Model
Multilayer Effects
– Model complex dielectric media
– Stratified layer division
– Vegetation and subsurface scattering
