摘　　要：文中给出了聚四氟乙稀、喷砂铝板、光滑铝板、4 8#砂纸、32 0 #砂纸、食盐等各类材料 ,针对 1 0 6 μm激光且入射角在不同条件下 ,反射功率随入射光线与目标法线夹角θ的变化关系。得到了聚四氟乙烯最接近朗伯体 ,而光滑铝板接近镜面的一系列有意义的结论。实验中发现喷砂铝板等多种材料均存在程度不同的反射峰 ,其中入射角等于反射角时砂纸在 4 3°～ 4 5°范围内存在奇特的反射峰。文中对研究散射特性实验方案的确定 。It is presented in this thesis that the varied relation between incidence angle and target normal clamp with reflecting power in the bistatic and monostatic lidar at 1.06μm about kinds of material, such as F4, sandblasted aluminum plate. And then, a series of meaningful conclusions are gained that F4 is the most closely Lambert Body but lubricous aluminum plate is resembled as mirror. In experiment, the different extent reflected peaks are discovered in many kinds of material, such as sandblasted aluminum, and there are peculiar reflected peaks between 43～45 degree in sand papers. It is described in detail how to ascertain the scattering\|characteristic experimental plan to research and how to compose experimental system.
