已有的森林反射模型［１－３］已经显示了其用于解释天顶方向观测到的森林遥感数据的能力。随着新的测量多角度反射特征的可能性的出现，大大地增加了在任意观察方向上模拟森林反射率的兴趣。上述模型也具有产生反射率方向分布的能力，但迄今仅有少量的应用。该文论述采用Ｎｉｌｓｏｎ和Ｐｅｔｅｒｓｏｎ［２］模拟模型的反射率方向分布的结果。
Existing forest reflection models [1-3] have demonstrated their ability to interpret forest remote sensing data observed in the zenith direction. With the advent of new possibilities for measuring multi-angle reflection features, the interest in simulating forest reflectivity in any direction of observation has been greatly increased. The above model also has the ability to produce reflectivity direction distributions, but so far only a small number of applications. This paper presents the results of reflectivity direction distribution using Nilson and Peterson [2] simulation models.
