摘要: 应用二向反射光度计实测了部分典型土壤在干燥与一定含水量状态下的偏振反射数据,并从探测方位角、光线入射天顶角、探测天顶角、偏振角、波段等几个方面对上述两种状态各类土壤的偏振反射特征进行了初步研究,对土壤遥感新方式做出了尝试。

Abstract: Polarized reflectance data of dry soils and soils containing 18% of water are collected with bi-directional reflectance detection instrument. The specialties of this instrument lies in its ability to measure the polarized reflectance of targets at various zenith viewing angles, incidence light zenith angles and azimuth angles with band A (630-690nm) and band B (760-1100nm). So analysis according those characteristics listed above is done. It is found that soils reflectance characteristics have direct relation with soil type, soil property and sensor's viewing geometry. This study on polarized reflectance of soils can not only help to find a new way for soil remotely detection but also provide the theoretical basis for further researches on the remote sensing of polarized light.
