Popis: Aiming at the problem of strong distribution regularity of false targets in traditional repetitive repeater deception jamming, this paper proposes a variable pulse width smart jamming method based on intermittent chaotic sampling from the perspective of changing the amplitude and position distribution of false targets. Firstly, the mathematical model of repeater deception jamming is deduced, and the reason of strong distribution law of false targets is explored. Then, the chaotic sequence fusion method is designed, and the fusion chaotic sequence is proposed to realize the purpose of non-uniform forwarding and destroy the amplitude regularity of the false target. Finally, the range of interference energy distribution is expanded by dexterous noise convolution modulation, and the position distribution of the false target is changed. The simulation results show that compared with the traditional repeated forwarding interference, the false target distribution law of the new interference pattern proposed in this paper is obviously destroyed, and it has better interference effect.
