| 摘 要： | 弹头和诱饵的微动特性存在差异,因此微多普勒特征分析在真假弹头目标的识别方面发挥了重要作用。文中在分析弹道中段导弹弹头不同微动形式引入的微多普勒效应的基础上,利用干扰机对接收到的雷达信号进行基于微多普勒特性的频率调制,生成虚假微多普勒信息转发给敌方雷达系统,从而实现欺骗式干扰。仿真实验表明,与常规噪声压制干扰相比,该方法可在较低干信比条件下对敌方雷达实施有效干扰。

| Abstract: | Due to micro-motion differences between warhead and decoys,the micro-Doppler signatures play an important role in target recognition.Based on the analysis of micro-Doppler effect induced by different micro-motion of missile warhead during ballistic midcourse,the jamming machine was used for frequency modulation of the received radar signals according to the micro-Doppler characteristics,and then the generated false micro-Doppler information was transmitted to the hostile radar system so as to achieve the in... |
