| 摘 要： | 本文简要介绍了地物二向性反射的概念及其与地物三维空间结构之间的关系。本文建议在建立高分辨率地物波谱数据库的同时,开展不同类型地物BRDF模型的研究。否则耗资巨大的数据库仍不能有效地应用于结构千变万化的环境遥感。

| Abstract: | This paper briefly introduces the concept of bidirectional reflectance and its relation to 3-D spatial structure of ground objects. It is suggested to develop appropriate BRDF models for various kinds of earth surface along with the process to set up a high spectral resolution data base for their signatures. Otherwise, it is pointed out, the costly data base can hardly deal with the great diversity of natural scene in composition and structure. |
