Forest biomass plays an essential role in forest carbon reservoir studies, biodiversity protection, forest management, and climate change mitigation actions. Synthetic Aperture Radar (SAR), especially...
DETECTION OF LANDSLIDES WITH SAR POLARYMETRY: CASE STUDY OF SOUTH-EASTERN COLOMBIA
Backscattering Coefficient Dispersion Mechanism Landslides Polarimetry SAR (PolSAR) Entropy – Alpha Parameter Classification Principal Component Analysis
2018/4/18
SAR polarimetry (PolSAR) is a method that can be used to investigate landslides. Polarimetric scattering power decomposition allows to separate the total power received by the SAR antenna, which is di...
热带人工林SAR散射组成及对遥感估测叶面积指数的影响
叶面积指数 后向散射系数 合成孔径雷达 RADARSAT
