在外场用已知半球反射率的靶板作为标准靶板，反演测定目标靶板激光雷达散射截面和半球反射率。
Using a plate whose hemisphere reflectivity is known as a standard plate, the lidar scattering cross section (LRCS) and hemisphere reflectivity of a target plate are measured inversely.
该方法利用半球谐基函数对入射光线正交化，利用两个半球上的笛卡儿积来定义物体表面的双向反射率分布函数。
This method USES the hemispherical harmonics basis to represent incoming radiance and USES the Cartesian product of two hemispheres to define the BRDFs.
氟碳油漆也能满足隔热降温性能指标要求，阳光反射率和半球发射率均大于80%3纳米ato既是红外辐射材料，又是导电材料。
Can meet the performance requirements of heat insulation and cooling, sunlight reflectivity and emittance are more than 80%3 of nano ATO is the infrared radiation material, and conductive material.
