摘　　要：采用基于频域矩量法(MOM)与解析法的AnsoftDesigner软件,计算、分析了导体圆盘基底烧结铁氧体隐身层因裂纹介质参数出现变异的雷达X波段高频电磁特性。采用V极化波和H极化波2种情况入射,分别计算与分析,得出:在8-12 GHz频带内,因裂纹产生介质参数变异对隐身电磁性能影响较明显。This paper discusses the problem that the cracks the coating of aircraft result in the variation of the medium performance index and thus affect the stealthy performance of aircraft.By using Ansoft Designer based on MOM and resolution methods,the calculation and analysis of radar X-band frequency wave high frequency electromagnetic characteristics are done when the medium parameter variation caused by cracks appear on the coating sinter ferrite stealthy layer of a perfect conductor disc base.By using V polarization wave incidence and H polarization wave incidence in calculation and analyses,the result shows that the infection is obvious on the stealthy electromagnetic performance because of the coating sinter Ferrite medium performance variation caused by cracks in 8-12 GHz.
