Abstract:
With the development of digital radio frequency memory(DRFM) and repeater jamming, the jammer can apply the multi-radar signal jamming technology to the interference forwarding of a single set of radars, the traditional design of radio frequency- screen fails to achieve expected result. Starting from the technical characteristics of DRFM, a new design based on waveform agility with multi-dimension is introduced to solve this problem. The diversity of active confrontation is enhanced through improving the number, switching speed of radar signal waveform, reducing the correlation between radar signal waveforms, combining waveform agility with radio frequency-screen, in order to consume the DRFM resources and reduce the intensity of interference. The effectiveness and feasibility of the new design is verified through simulation analysis and actual testing. The result shows that the anti-jamming effect of the new design is significantly improved compared to the traditional design of radio frequency-screen technology. The presented results provide a new perspective for the counter of repeater jamming.
