消光系数在雷达遥感中的作用
Reviewing the role of the extinction coefficient in radar remote sensing
摘要：
本报告重新审视了森林监测雷达后向散射模型中的消光系数的作用。对处理这个问题的一些工作的回顾揭示了灭绝值的多样性，其对传感器频率和森林类型的依赖尚不清楚。此外，一个后向散射模型直接来自RVoG制定分析的后向散射水平作为植被高度的函数的饱和度和存在的后向散射超出饱和点的下降趋势，在文献中以前的作品中所建议的。根据这一分析，似乎有理由认为，进一步的研究，特别是专注于专门的实验测量的消光系数应该进行。
英文摘要：
This report revisits the role of the extinction coefficient in radar backscattering-based models for forest monitoring. A review of a number of works dealing with this issue has revealed a diversity of extinction values being unclear its dependence on the sensor frequency and the forest type. In addition, a backscattering model directly derived from the RVoG formulation is employed to analyse the saturation of backscattering level as a function of vegetation height and the presence of a decreasing trend of backscatter beyond the saturation point as suggested in previous works in the literature. According to this analysis it seems reasonable to think that further research specially focused on dedicated experimental measurements of the extinction coefficient should be carried out.
