Radar Advantages
Cloud and smoke penetration.
Night vision.
Forest canopy penetration and canopy structure.
Complements visible/infrared sensors (sensitive to terrain features and moisture).
Good for discrimination of terrain structure (roughness) and drainage patterns.
Interpretation requires knowledge of radar interaction with surfaces.
Speckle (dark and bright pixels) limits interpretation.
Satellite systems are not yet multispectral and multi polarization (usually one band/one polarization) on most satellite platforms (limits forest canopy information).
Not good for discrimination and mapping of different vegetation types except at very general levels.
Data analysis can be hindered in steep topography and rough terrain due to extreme layover effects.
