光线

Directional Brightness Temperature of 3D row crop canopy generated by the Clumped Architecture Model of Plants were calculated efficiently and accurately based on the Persistence of Vision Raytracer software. Clumping index, average leaf angle and leaf area index are main parameters of CLAMP model. By analyzing the sensitivity of these parameters to DBT, the changing rules of DBT were found.

利用POV-ray光线追踪方法，对植被真实结构模型生成的复杂行播场景下的方向亮温进行快速演算，并针对CLAMP模型中集聚指数，平均叶倾角和叶面积指数，对冠层方向亮温的影响做敏感性分析，得到在不同参数输入条件下DBT的一些规律。
