| 摘 要： | 在常规目标的各种电磁散射源中,缝隙属于弱散射源.但对于隐身目标,缝隙的影响就不可忽略.为分析缝隙对目标电磁散射特性的影响,在三维理想导体表面上排布不同形状及数量的缝隙,采用矩量法结合RWG基函数,分析导体表面的电流分布,并计算其宽带雷达散射截面(RCS).对一系列雷达散射截面的分析,得到缝隙电磁散射特性随缝隙数量、形状、间距变化的规律.

| Abstract: | Among the various electromagnetic scattering sources of traditional objects,slits are feeble sources.But for the stealth objects,the scattering contribution of slits can't be ignored.To analyze the effects of slits to the electromagnetic scattering characteristics of objects,different sizes and numbers of slits were placed on the surface of three-dimensional perfect conductor.Method of moments in conjunction with RWG basis function was used to analyze the surface current density and wide-band radar cross section(RCS) of perfect conductor with slits.By means of a series of radar cross section analysis,the electromagnetic characteristics of slits were investigated when the number,size and interval of slits were changed. |
