| 摘 要： | 采用了一种偏振方法来测量土壤湿度,并改进了一种粗糙表面的偏振反射模型。利用该模型对土壤湿度的偏振特性进行了分析与实验,发现该模型模拟数据与实验数据之间存在很强的相关性,进而可以建立该模型中的某些参数与土壤湿度的定量关系,为定量反演土壤湿度提供新的途径。

| Abstract: | In agriculture,hydrology and meteorology,monitoring the soil moisture in real time and in the long term by the remote sensing technology is very meaningful.However,how to quantitatively retrieve the properties of objectives is a unsolved problem in remote sensing.A new polarimetric method,which is different from the traditional remote sensing by radiometry,was employed for retrieving the soil moisture.A scattering polarization model was developed to analyze the polarimetric characteristics of soil moisture.... |
