| 摘 要： | 提出了一种基于数字射频存储器的速度维多假目标欺骗干扰实现方案,论述了干扰信息的调制方法. 对调制速度维多假目标时需要较多资源的问题,采用了数据保持法来生成多普勒频率调制系数,分析了采用该方法所需要满足的约束条件.对干扰信号峰平比较高的问题,采用移相法进行了处理. 结果表明,该方法可以达到较好的低峰平比效果.

| Abstract: | A deceptive jamming method based on digital radio frequency memory(DRFM) is proposed.Multiple artificial targets jamming in velocity is realized.Modulation of jamming information is described in detail.Regarding the problem of too much resource needed when modulating multiple artificial targets in velocity,method of data holding is used,and the condition of using the method is analyzed.The problem of high peak to average power ratio when generating multiple artificial targets in velocity at the same range c... |
