Abstract

Biomass estimation plays an important role in the investigation of climate changes and global warming on terrestrial ecosystems. In recent years, related researches show POLINSAR techniques can significantly improve biomass estimation. Tree height can be estimated using POLINSAR techniques which by using that, the tree’s biomass can also be estimated. It is known that COHERENCE OPTIMIZATION has an effective role on improvement of tree HEIGHT ESTIMATION using POLINSAR. In this paper, various tree HEIGHT ESTIMATION methods, such as coherence amplitude INVERSION ALGORITHMS, DEM differentiating, and combined methods are validated and compared using simulated data. COHERENCE OPTIMIZATION methods which are applied in these algorithms are numerical radius and phase diversity COHERENCE OPTIMIZATION algorithms were estimated respectively. According to the fact that phase diversity algorithm was a phase based method, it didn’t have significant effect on improvement of tree height using coherence amplitude algorithm. However, improvement of tree HEIGHT ESTIMATION by DEM differentiating method is obvious. In comparison to the previous method, although numerical radius method is time consuming and has a complicated process but it improves tree HEIGHT ESTIMATION in great deals.
