摘要
针对自卫电子对抗射频隐身条件下功率管控问题,分析了自卫电子对抗中压制性干扰与欺骗性干扰的射频隐身特性,讨论了自卫电子对抗有效干扰及射频隐身的关系并建立了射频隐身特性模型,提出了压制比有效边界、信干比有效边界的自卫电子对抗功率管控方法。依据电子对抗的"互闭环"特性,建立了基于功率管控前后截获距离比值的射频隐身表征因子,通过仿真证明了功率管控方法的有效性。
For the power control problem of defensive electronic countermeasures（DECM） in the conditionof radio frequency（RF） stealth,the characteristic of blanketing jamming and deception jamming of DECMis analyzed. The relationship between effective jamming and RF stealth of DECM is discussed and models ofRF stealth characteristic of DECM are established. The power control methods of blanket ratio effectiveboundary and signal jamming ratio effective boundary are presented. According to the mutual closed loopfeature of electronic countermeasures,the RF stealth factor of DECM is established,which is the radio of in-tercept ranges before and after using power control methods. Simulation proves that power control methodsof DECM are effective.
