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。

Abstract：

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.
