Abstract
Forest height is an important indicator of the health of the forest ecosystem and can be utilized for accurate estimation of important parameters such as forest above-ground biomass. PolInSAR techniques have been utilized for forest height estimation using airborne and space-borne platforms. However, temporal decorrelation severely limits the ability of space-borne PolInSAR observations for meaningful height inversion. With the launch of the TerraSAR-X/TanDEM-X platforms, acquisition of Polarimetric SAR data in bistatic mode, without the undesired effects of temporal decorrelation, is possible. Full-PolInSAR bistatic data is acquired over Indian tropical forests and the height inversion results are presented in this research article. The inverted height shows a good correlation with field measured height, with r = 0.8. The inversion shows over-estimation over low height forests, while providing an accurate estimation for tall forested areas.
