| 摘 要： | 为改进标准抛物线方程算法的缺陷,本文基于Padé逼近引入高阶抛物线方程,结合复坐标系的完全匹配层(PML)吸收边界条件来求解多体目标的雷达散射截面,计算结果表明高阶抛物线方程不但可以有效地处理轴向方向40度以内的电磁散射问题,并且可以有效地对多体目标进行雷达散射截面计算,为计算电磁学提供了新的、有效的数值计算方法.

| Abstract: | A Padé approximations is introduced to handle high-order parabolic equation scheme for overcoming the shortcoming of standard parabolic equation for the first time.We compute the multi-object radar cross section (RCS) combined with perfectly matched layer(based on "stretched coordinate").Numerical results show that the wide-angle parabolic equation scheme can handle not only the scattering of electromagnetic within 40 degree along the paraxial axis,but can compute multi-object radar cross section(RCS) efficiently.Thus the scheme provides a new and efficient numerical method for computation electromagnetic. |
