| 摘 要： | 本文讨论了双向反射率分布函数、双向反射率、双向反射率因子等光谱反射率之间的关系,并指出了在一定条件下,遥感技术中野外测量地物反射光谱所得的双向反射率因子和物理学中惯用的光谱反射率即半球反射率定义(全部反射光功率与入射光功率之比)是完全一致的.最后还讨论了在野外测量地物反射光谱时需要注意的几个具体问题.

| Abstract: | The paper discusses the relationship among the bidirectional reflectance distribution function,bidirectional reflectance and ibidirectional reflectance factor;shows that in remote sensing technology the bidirectional reflectance factor calculated from the reflective spectrum of background object in field test is identical in definition to the conventional semisphere reflectance (the ratio of the total reflective light power to the incident light power)in physics under some conditions;and also discusses some... |
