本文提出了AIEM模型中的多次散射。推导过程在数学上比较复杂，但最终的表达式简洁，易于数值实现，只涉及一系列的二维积分。推导了后向散射中的一些特殊情况，并与已知的解析模型进行了比较，部分验证了修正后的AIEM模型在交叉极化中的有效性。最后，与数值模拟和现场测量的比较，以显示模型的性能和精度，特别是在交叉极化后向散射。
This paper presents a multiple scattering in the AIEM model. The derivation is mathematically intricate, though, the final expression is compact and easy for numerical implementation, which only involves series of two-dimensional integration. Some of special cases in backscattering are derived and compared with known analytical model to partly validate the update AIEM model in cross polarization. Finally, comparisons with numerical simulation and field measurements are made to show the model performance and accuracy, particularly in cross-polarized backscattering.
