摘要：
TomoSAR provides 3D information of complex targets such as forests. Space-borne SAR data utility for TomoSAR analysis is limited due to temporal decorrelation. A novel technique is introduced which utilizes multiple TanDEM-X data sets to generate accurate tomograms. The technique is demonstrated using multiple space-borne SAR acquisitions over Indian tropical forest. Cross-validation with PolInSAR estimation forest height and field height shows high accuracy of generated tomograms. Fully polarimetric space-borne X-band SAR data shows surprising capability to extract 3D scattering information of forested regions.
