摘要
针对PD雷达,研究了一种灵巧噪声干扰。该方法基于数字射频存储技术,将干扰机接收并存储的雷达发射信号与噪声信号进行卷积后转发出去,该干扰能量利用率高,能产生压制性和欺骗性双重干扰效果。仿真结果表明了该方法的有效性。
Aiming at PD radar, the simulation and analysis for smart noise jamming is studied. The method is based on DRFM technology. The received and saved transmitting signal is convolved with smart noise and then the processed signal is transmitted back. This kind of jamming signal not only can have the high utility of jamming power, but also can produce blanketing and deception jamming effects. The method is proved to be effective by a simulation example.
