摘　　要：反向交叉眼干扰是近年来受到广泛关注的一种单脉冲角度欺骗干扰技术,为丰富反向交叉眼干扰理论,对多干扰机场景下的反向交叉眼干扰技术进行了分析。在分析过程中,通过严格地推导,研究了反向交叉眼干扰性能与反向交叉眼增益的关系;在此基础上,研究了多干扰机协同干扰时,干扰机对间存在的相对幅相差以及目标回波对反向交叉眼增益的影响,进而分析了上述干扰因素对反向交叉眼干扰性能的影响。仿真结果表明,干扰机对间的相对幅相差变小、目标回波相对干扰信号的相对幅度变小时,反向交叉眼增益增强,反向交叉眼干扰效果增强。Retro-directive cross-eye jamming has caused lots of interests in recent years as a angle deception jamming technology against monopulse radar, in order to perfect the retro directive cross-eye jamming theory, the retro-directive cross-eye jamming technology under multiple elements scenario is analyzed. In the analysis procedure,the relationship between the retro-directive cross-eye jamming and retro-directive cross-eye gain is obtained by strict deriving. Then on this basis, the influence on retro-directive cross-eye gain caused by the rela-tive amplitude and phase error between jammers and target echo is researched under the multiple elements sce-nario , then the effect of those factors on retro-directive cross-eye jamming performance is analyzed. The simula-tion results show that the relative amplitude and phase difference between the jammers become smaller , the relative amplitude of the target echo relative to the jamming signal becomes smaller, the retro-directive cross eye gain will be enhanced, and the jamming effect of the retro-directive cross-eye jamming technology will be enhanced.
