摘　　要：针对干扰机难以对雷达产生具有较高威胁程度的假目标的情况,为提高假目标对真实目标的掩护效果,提出基于数字射频存储(DRFM)的假目标威胁等级提升方法。根据DRFM干扰原理归纳了3种干扰模型,结合"功率颠倒转发"的高度欺骗方法,调整干扰模型参数并完善假目标各方面信息。干扰实施流程的仿真计算结果显示,该干扰方法可以形成连续平稳的虚假航迹,且假目标威胁等级高于真实目标,验证了该方法的有效性。It is difficult for the jammer to generate a false target with a high degree of threat to interfere the radar. In order to improve the sheltering effect of false targets on real targets,a method for promoting the threat level of false target based on Digital Radio Frequency Memory（ DRFM） is presented. According to the operating principle of DRFM,three kinds of interference models combined with power reverse forwarding deception jamming are summed up. By adjusting the parameters of the interference model,all aspects of the false targets are improved. According to simulation calculation result of the interference implementation process,this method can form continuous and stable false tracks,and the threat level of false targets is higher than that of the real targets. Therefore,the validity of the method is proved.
