摘　　要：在准确分析目标隐身性能的基础上,对于目标面-线-面结构中导线与导体的连接问题,采用矩量法(MoM)进行分析。通过将结构中的导体与导线离散化,结合Costa基函数,很好地解决了目标面-线-面结构连接域中电流不连续的关键问题,获得了目标结构的矩量解和散射场。最后,通过Matlab编程与HFSS仿真进行比对,计算结果基本吻合,证明了结构中导线的引入使得隐身目标的电磁散射特性发生明显变化,并且验证了MoM法及Costa基函数在面-线-面结构散射场计算中的有效性和准确性,为隐身目标复杂结构散射特性研究提供了一种新的计算方法。In this paper,we present a new way to analysis the connection problem between a conductor and a wire in the surface-wire-surface structure of stealth targets using Method of Moments（MoM）.Combined discretion of the ideal conductor and wire with Costa basis function,a good solution for the question of current discontinuous in the connected area of the surface-wire-surface structure is carried out,the moment solution and the scattering field of the target are also obtained.Moreover,the simulation results conducted both by Matlab and HFSS for analyzing this proposed problem agree very well with each other,and it is demonstrated that the introduction of the wire can cause the obvious difference of electromagnetic scattering properties of the stealth objects.Correctness and validity of the MoM and Costa basis function is also verified when applying in calculating the scattering fields of the surface-wire-surface structure,which provides a novel approach for the research on scattering properties of the complex stealth structure.
