摘要: 在分析高重频脉冲信号特征的基础上,基于被动导引头前端工作流程研究了高重频脉冲的干扰机理,建立了干扰效能评估指标并仿真验证了分析结果。结果表明,前端模拟器件产生的瞬态响应和非线性失真是高重频干扰发挥效能的重要原因,合理设置信号参数可改善干扰效果。

Abstract: Based on the analysis of the signal characteristics of high pulse repetition frequency (PRF) pulse, a jamming mechanism of high PRF pulse is studied according to the working process of seeker fore-end; an evaluation index of interference effectiveness is set up and the analytic result is validated by simulation. The results show that transient response and nonlinear distortion produced by analogue devices are the main reason of interference; setting reasonable signal parameters can improve the effect of interference.

Key words: passive seeker, ultra wideband pulse, high PRF signal, transient response, jamming mechanism, nonlinear distortion
