  • 将散射介质层在z轴方向划分成薄层,用薄层的一阶散射强度、Fourier变换和迭代方法求解散射介质整层的矢量辐射传输(VRT)方程的高阶散射解.该方法将一阶散射与高阶散射迭代结合起来,计算公式简明,可计算高阶迭代解,计算时间少.计算结果与一层均匀散射介质的VRT方程一阶Mueller矩阵解、半空间均匀散射介质二阶Mueller矩阵解、以及离散坐标-特征值特征矢量法的VRT热辐射的数值解作了全面的比较.提出并讨论了非均匀散射层主动与被动VRT方程的高阶解.本计算程序可以通用于非球形粒子多层结构及非均匀介质的散射和热辐射计算.
    By stratifying a random scattering media into thin multi-layers in z direction,the first-order scattering solution of each thin layer with Fourier transform is employed to derive high-order scattering solution of the whole random media.An iterative approach to solve high-order scattering solution of a vector radiative transfer (VRT) equation is newly developed.Numerical results are well compared with the Mueller matrix solutions of the first-order for a layer medium,second-order for a half-space,and also the results of the discrete ordinates and eigen-analysis method.It demonstrates that our approach is as feasible,effective and especially applicable to high-order solutions of VRT for both bistatic scattering and thermal emission of inhomogeneous non-spherical scattering media.
