摘要
介绍转发式欺骗干扰系统,基于数字射频存储器系统的原理,确定了多目标欺骗干扰的总体设计思想,在此基础上设计了一种受高斯白噪声干扰的线性调频信号经过脉冲压缩匹配滤波后重构回波信号的模型,并详细论证该方案。通过对整个系统进行功能仿真和效果检验,结果表明,这种方案对于雷达实施干扰效果好,易于硬件实现。
The system of repeater jamming was introduced,and the idea of multi-false targets was determined based on the principle of Digital Radio Frequency Memory（DRFM）.The model of the LFM signal,with or without white Gaussian noise,to reconstruct return wave signal through a pulse compression matched filter was designed.The effect verification and the function simulation were also performed.The results show that the approach is effective to radar jamming,and easy to be implemented.
