摘　　要：隐身飞机的出现对导弹的作战能力提出了更高的要求,增大敌方目标自身雷达散射特性是未来导弹反隐身技术发展的一个重要方向。为了实现低RCS目标电磁增强,本文拟针对典型隐身飞机,基于电磁理论和导弹反隐身技术,设计了几种不同的目标RCS增强方案;利用基于多层快速多极子算法(MLFMM)的FEKO软件,计算、分析不同增强方案在低RCS目标载体上的RCS特性和增强效果,其结论为未来导弹反隐身技术和智能化导弹的发展提供参考。The emergence of stealth aircraft puts forward better requirements for the combat capability of missiles.Increasing the scattering characteristics of enemy’s stealth aircraft is an important development direction of antistealth technology of the future missile.In order to enhance the scattering of the low RCS target,this paper is based on electromagnetic theory and anti-stealth technology of missile,several different enhancement schemes are designed.The scattering characteristic and the enhancement effect at deferent band and azimuth are calculated and analyzed with FEKO software,based on multilevel fast multiple method(MLFMM).The conclusion provides reference for the development of anti-stealth technology and smart missile in the future.
