Abstract

Forest tree height is an important parameter of forest resources,so study on inversion of tree height of forest has important significance.This paper's data source has two full polarization data which were generated by PolSARPro software of ESA and two bands for the pretreatment,and the DEM difference method,RVOG phase method and the coherent amplitude method were chosen to reverse the tree height,finally analyzing and evaluating the result of L band and X band.The results show that for L band DEM difference method underestimates the tree height,RVOG phase method overestimates the tree height,the coherent amplitude inversion tree height precision is higher than DEM difference method and RVOG phase method,the X band badly underestimates the tree height and could not be applied to the three tree height inversion algorithm,the inversion result is not ideal.

Key words： PolInSAR; tree height inversion; DEM difference method; RVOG phase method; coherent amplitude method
