Paper Abstract

Tree height is an important biophysical parameter. It is a need for forest and biomass map for the estimation of carbon budget. Polarimetric SAR interferometry (PolInSAR) has been applied successfully to retrieve biophysical parameters from forest areas. In the real process, the retrieval result is not truthfulness because of non-volumetric scattering decorrelation scatterer. The scatterer is generated by coherence noise. The scatterer will be misjudged and mistook for a tree. Before Retrieving of Tree Height, non-volumetric scattering decorrelation scatterer needed to be removed. This paper will propose to combine the linear and optimization polarization interferometric coherence to remove the nonvolumetric scattering decorrelation scatterer. The retrieval results have been proved reasonable.
