A complex sequence intermittent sampling repeater jamming technique is proposed to improve the shortcomings of intermittent sampling repeater jamming, such as the difficulty of capturing the pulse leading edge of non-cooperative signals, limited duty ratio of jamming sequence and limited adaptability for various radar. Firstly, the jamming principle of intermittent sampling repeater jamming is introduced. Secondly, the complex sequence intermittent sampling repeater jamming technique is illustrated in three aspects, such as jamming sequence design, time domain jamming waveform design and frequency domain jamming waveform design; Finally, the jamming effect of this new jamming technique is simulated. The theoretical analysis and simulation results demonstrate that the proposed method is flexible, effective and extendable.
