Abstract：Phase-coded pulse compression radar can effectively identify and suppress intermited sampling repeater jamming by usinganti-jamming waveformand data post-processing technology.In order to avoid the discontinuityand periodicityof intermitted sampling repeater jamming and improve thejamming efect for radar， the phase-coded radar pulse compression principle and echo processing technology is introduced，and the corelation between the sequences of the same connection mode register in different initial states and the diferent connection mode register in diferent initial states is analyzed.On thebasis of the above mentioned，a jamming method based on the correlation characteristics of modulation sequence is proposed.By randomly selecting jamming sequences from the sequence list and adopting the direct modulation emision，the random falsetarget deception jamming or noise jamming efect can be generated. Simulation experiments verify the conclusions of the analysis，and the results show thatthe proposed jamming method has a good jamming effect.
