N2 - Polarimetric SAR Interferometry (PolInSAR) provides a useful tool for forestry parameters retrieval at L-band. Three-stage inversion process is a traditional way to retrieve these parameters, but it has several shortcomings while ground phase estimation is processed. In order to overcome these shortcomings, an algorithm of ground topography estimation using PolInSAR image by means of coherence set is proposed in this paper. The coherence region derived from numerical range is combined with RVoG model to obtain accurate estimation of ground topography. Simulated image and SIR-C image of forestry area are used to validate the proposed algorithm.
