基于间歇采样的时域乘积干扰研究

Research into Time-domain Product Jamming Based on Intermittent Sampling

间歇采样干扰是自卫电子对抗中常用的一种干扰手段,通过接收、存储、调制、转发对方的雷达信号对敌方的雷达进行欺骗性干扰。首先分析了间歇采样干扰原理,然后在此基础上研究了不同时域乘积调制下的间歇采样干扰特点。仿真表明,对间歇采样干扰进行时域乘积调制会形成更加离散的时域波形,更容易形成距离维提前的假目标。

Intermittent sampling jamming is a common jamming method for self-defense electronic countermeasures,which can perform deceptive jamming to the enemy radar by receiving,storing,modulating and retransmitting the radar signal of the other side.Firstly,the principle of intermittent sampling jamming is analyzed,and then the characteristics of intermittent sampling jamming in different time-domain product modulation are studied on this basis.The simulation results show that the time-domain product modulation of intermittent sampling interference can form more discrete time-domain waveform,and it is easier to form false targets ahead in distance dimension.
