基于TerraSAR-X/TanDEM-X数据的森林高度反演算法研究

基于RVoG模型，对传统三阶段算法及其改进算法进行研究，以云南省西双版纳州勐腊县为研究区，以TerraSAR-X/TanDEM-X数据为数据源进行森林高度反演算法研究，并结合野外实测数据进行结果验证。结果表明，三阶段改进算法对森林高度反演精度优于传统三阶段算法。三阶段改进算法对天然林高度反演精度较高；三阶段算法对橡胶林高度反演精度较高。

Forest Height Inversion Algorithm Based on TerraSAR-X/TanDEM-X Data

Based on the RVoG model, the three-stage algorithm and its improved algorithm were studied. In Mengla County, Xishuangbanna, Yunnan, TerrasAR-X/tandem-X data were used as data sources to conduct forest height inversion algorithm. Finally, the results were verified by field measurement data. The results showed that the accuracy of the improved three-stage algorithm was better than that of the traditional three-stage algorithm. For natural forest and rubber forest, the improved three-stage algorithm had higher accuracy in height inversion of natural forest. The accuracy of the three-stage algorithm for rubber forest height inversion was high.
