摘　　要：脉冲多普勒引信具有距离和速度二维选择能力,使其具有很强的抗干扰能力。为了提高对脉冲多普勒引信的干扰效果,在分析其基本工作原理的基础上,提出了基于多普勒调制的速度多假目标干扰。给出了产生速度多假目标的基本原理,推导了速度多假目标干扰下脉冲多普勒引信的输出,并对速度多假目标干扰的干扰效果进行仿真分析。理论分析和仿真结果表明该方法能够在速度维对脉冲多普勒引信形成多假目标干扰,且假目标的数量和参数能够根据干扰需要进行灵活控制,能够有效干扰脉冲多普勒引信。Pulse Doppler fuze has the ability of distance and velocity measurement, which make it have strong anti-jamming capability. In order to improve the jamming effect to the pulse Doppler fuze, a multiple velocity false targets jamming method based on Doppler modulation was designed based on analysis to its working principle. The working principle of multiple velocity targets generating was proposed, then the output of pulse Doppler fuze under the jamming of multiple velocity false targets was derived. Simulations were made to analyze the jamming effect of multiple velocity false targets. Theoretical analysis and simulation results demonstrate that this jamming signal can produce multiple false targets with different velocities and the jamming parameters can be altered flexibly according to the requirement. It is proved that this method can jam the pulse Doppler fuze efficiently.
