摘　　要：瞬时测频(instantaneous frequency measurement,IFM)接收机具有截获概率高、瞬时带宽大、分辨率高等优点,被广泛应用于雷达告警、雷达侦察等电子对抗设备。因此对IFM接收机的干扰能有效提高雷达的生存概率。给出了IFM接收机的结构,分析了同时到达信号对IFM接收机测频的影响,最后提出了使用连续波射频掩护信号干扰IFM接收机测频工作的方法,并且在SyetemVue平台上对该方法进行了仿真实现,仿真结果验证了方法的有效性和不同条件下连续波掩护信号对IFM接收机的干扰效果。IFM（ instantaneous frequency measurement） receiver has many advantages,such as high probability of interception,large instantaneous bandwidth and high resolution. It has been widely used in radar warning,radar reconnaissance and other electronic warfare equipment. Therefore,the interference to IFM receiver can effectively improve the survival probability of radar. Based on the analysis of IFM principle,the method of using continuous wave radio frequency-screen signal to interfere with frequency of IFM receiver is put forward,and the simulation of the method is realized on the Syetem Vue platform.The jamming effects under different conditions of continuous wave signal on IFM receiver are verified.
