摘要
运用经典的基尔霍夫近似研究了高斯粗糙面的电磁散射。根据基尔霍夫近似理论,得到了单站情形下,不同极化状态、不同介电常数、不同粗糙面情况的后向散射截面,得到了后向散射截面随以上参数及入射角的变化而变化的数值结果,分析了结果的物理意义;同时也得到了双站情形下,不同极化状态、不同介电常数、不同入射角、不同方位角的散射截面,得到了散射截面随以上参数的变化而变化的数值结果,分析了结果的物理意义。
The electromagnetic scattering from Gaussian rough surface is studied by applying the KA (Kirchhoff Approximation). According to the KA, the different polarization backscattering coefficients for different rough surface cases are obtained. Meanwhile,the bistation scattering coefficients for different cases are also evaluated. Finally,numerical illustrations are carried out for the characteristics of the mono and bistation scattering coefficients and its physics meaning of result is analysed.
