摘要
针对传统间歇采样转发干扰样式在面对具有较强抗干扰能力的新体制雷达时,因其波形较强的规律性而易被识别并剔除的问题,提出了一种非均匀采样与波形重构的方法对干扰波形进行优化。本文基于传统间歇采样转发干扰产生过程,在雷达信号采样过程中,采用非均匀方法完成信号相干采集;在干扰信号生成过程中,采用组合重构的方法完成干扰波形生成。论文通过Matlab仿真实验对使用方法进行了验证,与传统方法相比,提出的优化方法具有更好的干扰效果与抗识别特性。
Traditional interrupted-sampling and repeater jamming scheme is easy to be identified and eliminated by new system radar with strong anti-jamming capability because of strong regularity of its waveform.In this paper,a method featuring non-uniform sampling and waveform reconstruction is proposed to optimize the jamming waveform.Based on the generation process of traditional interrupted-sampling and repeater jamming,this paper adopts a non-uniform method to complete coherent signal acquisition in the radar signal sampling process.In addition,a combination-based reconstruction method is used to complete jamming waveform generation in the jamming signal generation process.The proposed method is verified through a MATLAB simulation test.It has better jamming effect and anti-identification characteristics than the traditional method.
