Polarimetric interferometric synthetic aperture radar (POLInSAR) has been used to extract the forest height successfully. Leaf area index (LAI) is an important parameter for the estimation of forest biomass, however presently the most of LAI extraction approaches are based on optical data. For the dense forest, the optical image is mainly the reflection of the canopy surface, and it is saturated easily for the LAI retrieval. Microwave has the relative long wave length, can penetrate into the… CONTINUE READING
