基于FPGA的雷达欺骗干扰信号调制器的设计

Design of a Radar Deceptive Jamming Modulator Based on FPGA

摘要: 提出了一种雷达欺骗干扰信号调制器的设计方案,给出了其在可编程门阵列(FPGA)中的实现结构。该调制器在单片FPGA中实现,能够宽带接收雷达信号,可对雷达实施欺骗干扰,并具有瞬时带宽大,干扰调制实时及干扰效果好等特点。在与单部警戒雷达的对抗实验中已取得较好的欺骗干扰效果,可应用于电子战远距离支援干扰。

Abstract: The design concept of a radar deceptive jamming modulator is presented,and its implementation structure based on FPGA is put forward.The modulator implemented in single FPGA can receive radar signal in wide band and transmit deceptive jamming to radar.It has many advantages,such as wide instantaneous bandwidth,real-time jamming modulation,perfect jamming effect and so on.In the experiment of jamming single guidance radar,good deceptive jamming effect had been achieved.It may be applied to stand-off jamming in electronic warfare.
