摘要
提出了一种新的数值方法,使得逆向蒙特卡罗法不但可以计算总辐射强度,还能计算直接强度和介质强度.在此方法的基础上,提出了一种改进的方法:光子分类法,该方法既能更详细地计算辐射强度组分,又能大大减少计算时间;然后比较了新方法和多射线法在计算辐射强度组分时的结果;最后将光子分类法应用于分析卫星遥感大气订正中的邻近效应问题.
A numerical method proposed by the authors made it possible that the backward Monte Carlo method is able to calculate the direct and medium intensities as well as the total radiative intensity. On the basis of this study, an improved method, named classifying-photons method, is proposed. The new method is able to calculate more detailed radiative intensity components, and costs much less CPU time. Then the new method and the multi-rays method are compared in computing radiative intensity components; In addition, the new method is applied to analyzing the adjacency effect in atmospheric correction of satellite remote sensing.
