A multiple false targets method based on interrupted-sampling and nonuniform periodic repeater jamming (ISNPRJ) and against to the linear frequency modulation (LFM) pulsed radar with mean level (ML) CFAR detector is proposed.Firstly
the principle is illuminated which takes advantage of the interrupted sampling and repeater jamming (ISRJ) to realize the distribution of multiple false targets.After that several key parameters both the number and the SNR of the false targets are derived.Then jamming effectiveness of the ISNPRJ is analyzed on the basis of the mathematics principle of the interrupted-sampling and periodic repeater jamming (ISPRJ)
meanwhile
numerical value of the sampling interval
the sampling pulse width
transmitted pulse width and the transmitted power are calculated.Simulation results show that ISNPRJ can reduce the detection probability of target greatly and jam the radar's detector effectively.
