Abstract

Polarimetric SAR Interferometry (PolInSAR) becomes a hot topic for forest parameters such as forest height inversion in SAR research areas, it is necessary to analyze the affect of polarization error on estimation accuracy. In this paper, polarization error transfer link of typical inversion algorithm is investigated, based on which the impact of polarization error on the inversion result of the algorithm is presented. The result is verified by simulation, and by which, the important theoretical basis and reference value are provided for inversion accuracy analysis, and quantitative calibration requirement is proposed.
