| 摘 要： | 论述了当前被动微波植被辐射模拟算法的进展和研究趋势.植被辐射的模拟方法主要分为3类:第一类是将植被看作各向同性的单层介质,光学厚度、单次反照率等设为常数或用经验关系来计算;另外两类主要差别在于冠层定义的方式不同.其中一种方法将植被冠层看作连续介质,另一种方法用植被冠层的离散特征(如茎和叶子的长度、方位)来定义.

| Abstract: | The effect of microwave radiation on vegetation is important for identification of land parameters. Because of complexity of vegetation, it is a difficult topic for research. This paper reviews the simulation of the vegetation canopy in passive microwaves. Various vegetation canopy models are discussed and compared. They can be grouped into 3 types. In the first type, the vegetation is considered as a uniform layer with constant opacity or albedo and simple formulas or empirical relationships can be used fo... |
