摘要
本文介绍了地物的二向性反射分布函数（ＢＲＤＦ）及共数学模型，讨论了ＢＲＤＦ的某种特定子集与地物结构的某些重要特征之间的关系，即地物结构的方向谱。为了描述ＢＲＤＦ的方向谱，作者选择并定义了信息量最为丰富的两个子集。即主平面子集和主锥面子集。还介绍了观测上的最新进展。
In this paper authors introduce the concept of bidirectional reflectance and its relation to 3-D spatial structure of ground objects. It is suggested to develop appropriate BRDF modes for various kinds of earth surface along with the process to set up a high spectral resolution data base for their signature. Otherwise, it is pointed:out, the costly data base can hardly deal with the great diversity of natural scene in composition and structure. Also the author gives a revise to Strahler-Jupp model and introduce the new progress of bidirectional reflectance measurement.
