Study of Intermittent Sampling Repeater Jamming to SAR

As a clever jamming mode,the intermittent sampling repeater jamming can produce multi fronted and lagged false targets,which forms the jamming effect of lifelike coherent false target series.Based on the mathematical principles of intermittent sampling repeater jamming,the output of SAR intermittent sampling repeater jamming is derived in details.Afterward,the influence of the sampling interval,duty ratio and repeater mode on the jamming performance is analyzed.The analyses are verified by simulation experiments.The research is very important for producing multi false targets in range direction to SAR.
