摘　　要：为了对抗具有强抗干扰能力的脉冲多普勒引信,通过分析脉冲多普勒引信的基本工作原理,确定了有效干扰脉冲多普勒引信的基本条件,在此基础之上,提出了基于DRFM的循环转发干扰以实现对脉冲多普勒引信的欺骗干扰。为了验证该方法的有效性,设计了仿真实验,仿真结果表明该方法产生的干扰信号满足有效干扰脉冲多普勒引信的基本条件,基于DRFM的循环转发干扰能够有效干扰脉冲多普勒引信。In order to counter PD fuze with excellent anti-jamming performance, the basic working principle was analyzed, on the basis of the analysis, essential conditions of jamming PD fuze were determined. Based on the essential conditions, the circular-repeater jamming technique based on digital radio frequency memory （DRFM） was presented in order to jam PD fuze. In order to verify effectiveness of the approach, simulation was designed. The results of simulation demonstrate that the jamming signal based on this technique could satisfy the essential conditions, and the circular-repeater jamming technique based on DRFM countering PD fuze is valid.
