Tropical forest aboveground biomass estimation based on vertical structures extracted with tomosar

The objective is to estimate forest above-ground biomass (AGB) considering the vertical structures of tropical forest in Mondah test site. Ten DLR F-SAR P-band fully polarized images are utilized to reconstruct the vertical reflectivity through TomoSAR techniques, and then extract multi-feature parameters from vertical profiles of reflectivity, finally these parameters are used for forest AGB estimation with support vector regression (SVR) approach. The results show that the method we proposed for tropical forest AGB estimation is effective and accurate in our test site.
