| 摘 要： | 利用矩量法（ＭＯＭ）和等效边缘电磁流方法（ＥＥＣｓ）研究波导馈电的缝隙天线阵的双站散射问题。从理论和计算上分析，等效边缘电磁流方法可以计算有限尺寸的导体平板沿任意方向上的双站散射（包括边缘绕射场），而矩量法可以考虑波导缝隙天线阵的散射与耦合问题，使它们混合便可以解决有限尺寸缝隙在线阵的散射问题。实际计算表明，方法是切实可行的。

| Abstract: | A hybridization method of moment(MOM) and equivalent edge currents(EECs) is presented to study the bistatic electromagnetic(EM) scattering from the slot antennas fed by the waveguides with arbitrary terminations.The EECs is applied to calculate the EM scattering of a conducting plane, including the diffraction of edge, while the MOM is used to obtain the fields in the slots and deal with the coupling between them. In conjunction with them, the EM scattering of the slot antennas can be evaluated. Several results are presented, demonstrating the applicability of this technique. |
