摘　　要：极化干涉SAR森林高度反演是当前雷达遥感领域的研究热点,近年来涌现了多种极化干涉SAR森林高度反演方法。本文先对已有极化干涉SAR森林高度反演方法进行分类,然后系统研究各类森林高度反演算法的基本原理,比较各类森林高度反演方法的优缺点,提炼森林高度反演算法的关键,最后指出极化干涉SAR森林高度反演的研究方向。Inversion of vegetation parameters by polarimetric interferometric SAR has attracted considerably increasing interest in the field of radar remote sensing and many methods of inversion of vegetation parameters have been proposed. In this paper, these methods are classified to four classes firstly . Then the basic theories of these methods are systematically studied. After- wards, the estimated performances of these methods are compared and the advantages and disadvantages of these methods are pointed out. Then the key techniques of Inversion of vegetation parameters are abstracted. At the end, the future research fields are proposed.
