本研究的目的是在扩展现有的基于积分方程面散射模型(IEM)的基础上，发展一种包含多次散射的面散射模型。这是通过去除IEM表面散射模型散射场表达式中使用的格林函数的谱表示中的简化假设来实现的，值得注意的是，尽管这种简化假设在单次散射计算中是有效的和有用的，但它阻碍了分离和识别导致表面多次散射的项，此外，证明了取消该假设允许进行多次表面散射计算，并被证明与从已知表面获得的受控实验室测量结果一致。
The objective of this study is to develop a surface scattering model including multiple scattering based on extending an existing integral-equation-based surface scattering model (IEM). This is done by removing a simplifying assumption in the spectral representation of the Green's function used in the scattered field expression of the IEM surface scattering model, It is noted that while this simplifying assumption is valid and useful in single scattering calculation, it is a hindrance to separating and identifying terms responsible for surface multiple scattering, Furthermore, it is demonstrated that the removal of this assumption permits multiple surface scattering calculations to be carried out and shown to agree with controlled laboratory measurements acquired from known surfaces.
