| 摘 要： | 为了正确识别雷达欺骗干扰,针对基于数字射频存储器(DRFM)及直接数字频率合成器(DDS)产生距离-速度同步拖引干扰的现代欺骗干扰机,根据干扰机的工作机理,理论推导并对比了理想距离-速度同步拖引干扰信号及实际干扰信号的频谱特征。发现实际干扰信号的最大谱线相对理想干扰信号会产生微小频偏并在幅度上有一定衰减,这一频域细微特征可以为雷达识别该类干扰提供依据。仿真实验验证了理论分析的结果。

| Abstract: | According to the principle of a modern deceptive jammer,which can generate a simultaneous RGPO and VGPO jamming signal based on DRFM and DDS architectures,the frequency spectrum of the jamming signal generated by one such jammer is derived.Then,by a comparison between this frequency spectrum and another spectrum of a jamming signal generated under an ideal condition,it can be found that the highest peak of the true jamming signal spectrum has an additional offset,and the amplitude of it is attenuated a little.This feature of the jamming signal in the frequency domain is helpful for radar to identify the occurrence of the jamming.The simulation results verify the analyses. |
