Research On Jamming Technology Based On Digital Radio Frequency Memory

New system Radar have good performances and ECCM capability, makes the conventional noise jamming and deception jamming failed. DRFM is the best sources of noise and deception jamming, it has become powerful means to counterwork new system Radar.This paper introduces the pulse compression, side lobe cancellation, clutter suppression, pulse accumulation and CFAR of coherent Radar signal processing. From the point of view of application, this paper also describes the principle of DRFM. Incorporated with jamming modulation technology, this paper studies the theory of jamming technology based on DRFM in detail, focused on the research of Doppler frequency modulation using digital orthogonal mixing method. On the base of analysis and research of DRFM technology, this paper presents some simulation experiments. The simulation results proved that frequency shift jamming is an effective jamming method on PC Radar.
