An approach to estimate tree height of coniferous forest in mountainous areas at plateau was developed using a combined function. One pair of dual Pol- InSAR images acquired on 20 June 2007 and 5 August 2007 by Advanced Land Observing Satellite Phased Array L-band Synthetic Aperture Radar (ALOS-PALSAR) sensor over Zoige plateau, northwestern Sichuan, China was used to evaluate the approach. The derived heights indicated that the combined function approach well compensated for underestimated canopy depth using the phase center methods. Thus, tree heights were better approximated in comparison with actually measured tree heights.
