摘　　要：极化干涉SAR综合了干涉SAR和极化SAR的优点,被广泛应用于植被高度的反演。对已有的四种基于极化干涉SAR的植被高度反演算法进行了论述,利用PoLSARpor进行仿真数据实验,对比分析了四种植被高度反演算法的优缺点及其适用范围。最后指出极化干涉SAR技术有待进一步研究的方向和问题。为选取基于极化干涉SAR的植被高度反演算法提供参考。The Polarimetric SAR interferometry has been widely used in forest vegetation height inversion with the integrated advantages of interferomelry SAR and polarization SAR. Four kinds of existing principles of vegetation height inversion algorithms based on polarimetric SAR interferometry were discussed and the PoLSARpor simulation data test was used to compare the advantages and disadvantages of four vegetation height inversion algorithms. Final ly the direction and the problems in further study of polarimetric SAR Interferometry Technology were presented. This paper serves a certain reference value for selecting the vegetation height inversion algorithm in light of polari metrie SAR interferometry.
