摘　　要：针对传统重复转发式欺骗干扰中假目标分布规律性强的问题,从改变假目标幅度与位置分布角度出发,以间歇采样重复转发式干扰为基础,提出了一种基于间歇混沌采样的变脉宽灵巧干扰方法。首先,推导转发式欺骗干扰数学模型,探究假目标分布强规律原由;然后,设计混沌序列融合方法,实现非均匀转发目的,破坏假目标的幅度规律性;最后,通过灵巧噪声卷积调制拓展干扰能量分布范围,改变假目标的位置分布。仿真结果表明,相较于传统的重复转发式干扰,本文所提新型干扰样式的假目标分布规律被明显破坏,具有较好的干扰效果。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.
