中文摘要：
以玉米冠层为研究对象,首先利用偏振反射机理分析了玉米冠层的反射信息中存在偏振现象;随后在抽穗前不同生长时期垂直观测方向对其高光谱偏振信息进行了测量,证明了理论推导,而且发现偏振光在总的反射光中所占的比例可达10%。这即表明了偏振测量可以为对地遥感提供辅助信息,同时也说明利用偏振信息反演大气参数时应该考虑地表偏振对它的影响。
英文摘要：
In the present study,corn canopy is the objective.Firstly the polarization of corn canopy was analyzed based on polarization reflection mechanism;then,the polarization of canopy was measured in different growth period at nadir before heading.The result proved the theoretical derivation that the light reflected from corn canopy is polarized,and found that in the total reflection the polarization light accounts for up to 10%.This shows that polarization measurement provides auxiliary information for remote sensing,but also illustrates that the use of the polarization information retrieval of atmospheric parameters should be considered when the surface polarization affects on it.
