  • 提出一种解析的随机泛函方法(SFA),计算导体Gauss粗糙面上三维导体目标的复合电磁散射.推导粗糙面的随机Green函数,用一种新的四路径模型描述面体复合散射机理,用SFA求解双站差场雷达散射截面.以导体球目标为算例,与其他数值计算方法比较后验证了SFA的有效性与准确性,同时讨论了粗糙度、体目标尺寸以及距离粗糙面高度等参量变化对结果的影响,给出复杂形状体目标的双站差场雷达散射截面的空间角分布.
    A stochastic functional approach (SFA) is developed to calculate electromagnetic composite scattering from a three-dimensional perfectly electric conducting (PEC) target on a randomly rough PEC surface. The stochastic Green's function for randomly rough surface is derived, and a novel four-path model is presented to describe the scattering mechanism of target-surface interactions. The SFA is used to obtain the difference scattering cross section due to the rough surface of target. As a simple example of a spherical target with rough surface, the SFA is numerically compared with other numerical approaches, showing its accuracy and effectiveness. Finally, the difference bistatic scattering from a complex electric large target with rough surface and its functional dependence on the parameters are discussed.
