| 摘 要： | 基于改进的微分近似法以及大气辐射DOS ISW算法，提出了用于大气订正的一种简单而精确的计算向上辐射强度的算法——多射线法，即对于沿着每一个投射到遥感器上的方向，分别用几个完全相同的带无穷小加权的离散方向来代表总辐射强度以及程辐射等组分，该算法考虑了地-气交互作用，可计算到任意高的精度，还可同时计算从任意方向投射到空基或地基遥感器上的辐射强度组分．

| Abstract: | On the basis of the modified differential approximation and the DOS ISW atmospheric radiation algorithm, a simple and accurate algorithm, named multi rays method, was developed for calculating radiative intensity components of atmospheric correction. For each direction incident on the remote sensor, several identical discrete directions are employed to represent the total intensity and path intensity respectively. This algorithm enables the computation of the surface atmosphere interaction, and high precision can be achieved as required. The present method is also used to calculate radiative intensity components incident on air based or ground based remote sensor in arbitrary directions. |
