| 摘 要： | 研究和提出了一种利用全极化干涉数据对植被高度进行反演的改进的三阶段反演算法。该算法结合三阶段反演算法和极化干涉数据的相干区域边界提取技术来估计体去相干值,以提高体去相干估计的精度,进而得到更加精确的树高反演结果。最后,利用欧空局(ESA)提供的模拟的L波段极化干涉合成孔径雷达(SAR)数据,通过计算机仿真,验证了算法的有效性。

| Abstract: | A refined algorithm of three-stage inversion process for polarimetric SAR interferometry was investigated and proposed. The coherence region extraction algorithm was combined with the three stage inversion algorithm to obtain more accurate estimate of volume decorrelation. The proposed algorithm could get more accurate inversion results. The method was applied to simulated coherent L-Band full polarimetric SAR data provided by ESA,and the validity of the modified algorithm was confirmed by simulation. |
