    冠层反射的简化模型

    (1)   Dymond和Qi (1997)将厚植被冠层的辐射模拟为三个函数的乘积:

    式中，S(i,e) 是冠层中阳光照射的比例，不包括互遮蔽部分;  是热点函数，针对冠层表面的互遮蔽性质对S(i,e)加以修正;而是阳光照射的叶片的平均辐射。3个函数给为:

       

    式中,i是入射角; e是出射角; 是相角(由太阳、目标、观察者构成); 分别是在入射方向和出射方向上的叶片投影面积; h是控制热点宽度的常数;w是二倍叶片反射率; E是太阳辐射通量密度。

    (2)假设叶片的方位随机分布，对可见光，辐射可表示为: 

      

    方程可推广到近红外光的多重散射情形:

      

    式中，k是参数。
