摘    要:对于携带电小结构的电大目标的散射问题,单纯的矩量法(MoM)或单纯的物理光学法(PO)由于自身固有的缺点,都不能给出有效的结果.而矩量法与物理光学法的混合方法是解决此类问题的有效途径,本文在MoM-PO混合法的基础上,通过引入等效电磁流方法(MEC)来计算PO区域边缘的绕射贡献,提出了一种MoM-PO-MEC混合方法,并将其计算结果与多层快速多极子计算结果进行比较,最终证明了该混合方法的有效性.

关 键 词:矩量法  物理光学法  等效电磁流法  混合法  雷达截面积  混合法  组合  体散射  应用  Body  Composite  Scattering  Hybrid  Method  有效性  比较  多层快速多极子  绕射  边缘  区域  计算  等效电磁流方法  散射问题  混合方法  结果  物理光学法

Abstract:As for the EM scattering problems of electrically large targets with electrically small structure, accurate results could not be obtained efficiently if MoM and PO method with some inherent disadvantages were used separately. As a result the MoM-PO hybrid method was studied in this paper, dealing with the problem mentioned efficiently. Based on this hybrid method, the MEC was used to calculate the diffraction contributions, and a new hybrid method MoM-PO-MEC was presented. Finally, it is proved that this hybrid method is efficient by comparing the simulation results with the MLFMA numerical results.
