| 摘 要： | 在光学遥感数据的应用过程中,地表太阳辐照度的量化问题对于遥感数据的获取和地表地物特性的反演等工作都是一个非常重要的环节,而地表太阳辐照度的定量计算又依赖于辐射源、目标物和传感器三者之间的几何关系以及目标地物的地表特征。利用山区地表太阳辐照度的计算模型,对不同时间、不同山区地形下的地表太阳辐照度进行了定量模拟,用三维图的方式分析了地表太阳辐照度随时间、地形坡度、坡向的变化规律,为光学遥感中地表太阳辐照度随时空变化的量化关系分析提供了更直观的依据。

| Abstract: | In the application of the remote sensing data,the quantity of surface irradiance is very important in the acquisition of remote sensing data and retrieval of surface character,but the quantity of surface irradiance is based on the geometrical relationship of light source,objects,sensor and the surface character of objects.Based on the model of terrain surface irradiance,the terrain surface irradiance with different temporal and spatial distribution was quantitatively simulated.The law between the surface ir... |
