为提高对伪码调相引信的干扰效果,提出了基于数字干扰合成(DJS)的数字多时延干扰信号合成方法,该方法可以极大提高干扰伪码调相引信的干扰效率。理论分析与仿真实验表明,该方法合成的干扰信号能产生不同时延的多假目标的干扰效果,兼具有欺骗干扰和压制干扰的效果,能够使干扰自动对准引信的频带并获得脉冲压缩处理增益,提高干扰能量的利用率。

The digital multi-delay smart jamming based on Digital Jamming Synthesis(DJS) is proposed in order to improve the jamming capability against pseudo random code phase modulation fuze. This method could improve the effectiveness of jamming against the pseudo random code phase modulation fuze. Theoretical analysis and experimental research demonstrate that this method can produce multiple false targets with different time delays, which has both deception and blanket jamming effects. This method can make the jamming frequency in accordance with the frequency band of fuze, and the jamming signal can acquire pulse compress gain of fuze. It can make use of the jamming energy efficiently.
