Abstract
With the information of interferometric coherence coefficient of different polarization states, Polarization Coherence Tomography (PCT) technology can reconstruct the vegetation vertical structure, it is an important development direction of SAR technology applications. This paper first introduced the principle of PCT, and then summarized vegetation vertical profile reconstruction process of PCT, and finally studied the applicable of PCT technology for stand height estimation with the simulation data and ALOS PALSAR data of Tahe region, the experiment results show that the estimation stand height of PCT is accurate, this technology has strong robustness, whenever choose which ALOS PALSAR data as the master image for registration, the effect on the estimation results are relatively small.
