摘要 为快速数值计算动态粗糙分形海面上有船目标时的双站散射,该文将广义前后向迭代法(GFBM)与谱积分加速算法(SAA)结合用于求解磁场积分方程(MFIE)。避免了电场积分方程(EFIE)数值计算的不稳定性。数值模拟了TE锥形波低掠角入射在一维动态分形粗糙导体海面以及船目标存在时的双站散射,讨论了多次散射传播的双站散射与动态分形海面和船目标各特征参数的关系。 A Generalized Forward-Backward Method (GFBM) with Spectral Accelerate Algorithm (SAA) to solve the Magnetic Field Integral Equation (MFIE) is developed. It is applied to numerical simulation of bistatic scattering from one-dimensional fractal dynamic sea surface with a ship presence under the TE tapered wave incidence at Low Grazing Angle (LGA). Numerical simulations of bistatic scattering at LGA show the functional dependence upon the fractal dimension of conducting rough surface, ship location and other parameters.
