在反射、散射和透射电磁辐射的过程中,植物叶片表面将产生与它们自身性质有关的偏振特征,完全可以作为遥感信息中有价值的信息来源.多角度对地观测能获得更为详细可靠的地面目标三维空间结构参数,使定量遥感成为可能.对植物叶片的多角度偏振高光谱探测成为定量遥感中的一种新手段.在分析植被叶片的多角度偏振高光谱特征基础之上,设计了一个3因素2水平的正交试验.通过对实验数据的方差分析发现,偏振角、入射天顶角、叶绿素以及三个因素之间的交互作用都可以对植物叶片的偏振反射产生影响,偏振角和入射天顶角对植物叶片的影响特别显著,二者的交互作用也有显著的影响.因此在今后的研究中,既要考虑单因素本身对植被叶片的偏振反射的影响,还要考虑到交互作用所起到的影响.
In the process of reflection, scattering and transmission of electromagnetic radiation, plant leaf surfaces will produce polarization characteristics related to their own properties and can be used as valuable information sources in remote sensing information. Multi-angle Earth observation can obtain more detailed and reliable The three-dimensional spatial structure parameters of ground targets make the quantitative remote sensing possible.The multi-angle polarization hyperspectral detection of plant leaves has become a new method in quantitative remote sensing.On the basis of analyzing multi-angle polarization hyperspectral characteristics of vegetation leaves, A 3-factor, 2-level orthogonal experiment was conducted to find out that the interaction of polarization angle, incident zenith angle, chlorophyll and all three factors can affect the plant’s leaf’s polarization reflection, and the polarization angle And the incident zenith angle on plant leaves is particularly significant, the interaction between the two also have a significant impact.Therefore, in the future study, it is necessary to consider the single factor itself on the impact of vegetation leaf polarization reflection, but also to consider the interaction Effect of the effect.
