本文的目的是研究单基线极化合成孔径雷达干涉技术在森林地形结构遥感和测量中的应用。为此，介绍了一种适用于从干涉观测值估计森林参数的植被覆盖极化相干散射模型，并对其进行了讨论和验证。在此模型的基础上，提出了一种可以从单基线全极化干涉数据中估计森林参数，如树高、平均消亡和下垫面地形的反演算法。利用德国航天中心的E-SAR系统在L波段获取的全极化单基线实验数据，验证了该算法的性能。
The objective of this paper is to examine the application of single-baseline polarimetric SAR interferometry to the remote sensing and measurement of structure over forested terrain. For this, a polarimetric coherent scattering model for vegetation cover suitable for the estimation of forest parameters from interferometric observables is introduced, discussed and validated. Based on this model, an inversion algorithm which allows the estimation of forest parameters such as tree height, average extinction, and underlying topography from single-baseline fully polarimetric interferometric data is addressed. The performance of the inversion algorithm is demonstrated using fully polarimetric single baseline experimental data acquired by DLR's E-SAR system at L-band.
