Rock Multi-angle Polarized Reflectance Characteristics

With the development of remotely sensed data application,people began to interested in getting more information about the target odject,especially the three-dimensional information ,and so hyperspectral remote sensing and multianglar remote sensing came into being.No matter it is traditional romote sensing or hyperspectral remote sensing, there is still an important perimeter of light-polarization which has not been paid much attention and used for remote sensing. For any object in this world, in the process of reflection scattering and transimission there will exist polarization which is domination by its nature,that will provide some important information for remote sensing data. So the study on the polarization of target object is very important.It is an important way to acquire the information of modern remote sensing by studying the polarized light of target object. But research of multianglar rock polarized characteristic has the important meaning not only to the remote sensing investigation of rock mineral resourses but also to promotion of mensurable development of the remote sensing, and it is great significance of the sensor of the remote sensing.Though some work on the specialty of rock spectrum has been done,work on polarized light reflectance feature of rock has nearly been done nothing. For those reasons being above,this paper presents a large set of spectral signatures of the polarized reflectance acquired over different agrotype about the rock type. The structure of this paper is as following:1,The first part is mainly about data acquired over different types rock and analysis about the signature of their polarized reflectance; conclused the connection about the polarized reflectant,incidence angle,view angle,azimuth angle and wave band.2,The second is identified different types rock by utilizing the method of the neural network.
