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.
