摘　　要：在分析线性调频信号模糊函数的基础上,指出了利用频谱搬移达到产生虚假目标的可行性,并量化了频率偏移量和距离变化量之间的关系;分析了正弦调频干扰实现压制式干扰的原理。提出二维移频与正弦调频相结合实现对特定区域目标实现压制式干扰的方法,并且利用仿真实验验证了理论的正确性。Based on analysis of the ambiguous function of LFM signal,the feasibility to produce fake targets by shift-frequency was pointed out in this paper,and the relationship between frequency offset and range variation was quantized.The principle of barrage jamming implemented by sinusoidal frequency modulation is analysed.A new method to actualize barrage jamming to a given area,which combines 2-D shift-frequency and sinusoidal frequency modulation,is proposed.The correctness of the method is proved by the simulations.
