| 摘 要： | 提出了一种新的应答式干扰技术——正弦全波整流加权调频干扰。阐述了该干扰信号的产生机理，对其信号特点和移频的效果进行了分析。理论分析表明：根据相应参数的灵活选择，这种干扰能对线性调频雷达产生不同程度的假目标欺骗干扰和压制干扰效果，且需要较小的干扰功率。仿真实验证明了理论分析的正确性和实际应用的可行性。

| Abstract: | A new technique of transponder jamming is proposed which is named sinusoidal full wave rectification weighted frequency modulation jamming. Generation principle of jamming signal is being presented,its features and effect of frequency shift is analyzed. Theoretical analysis shows that this jamming can produce different degrees of false targets deceptive jamming and cover jamming effects,according to flexible choice of corresponding parameters and require lower jamming powers. The simulation results justify the correctness of theoretical analysis and the feasibility of practical application. |
