摘　　要：针对传统电子干扰器系统复杂、体积大、功耗高的缺点,文章设计了一种基于FXI规范的射频通信干扰器,FXI规范在FMC信号定义的基础之上,针对虚拟仪器领域的应用,定义了FXI模块的结构尺寸和FXI接口的专有信号组,提高了虚拟仪器模块的功能密度,从而实现了模块化、小型化和轻量化的设计目的;该射频通信干扰器内部同时集成了频谱仪模块和射频信号发生器模块,通过采用硬件逻辑实现射频信号的实时跟踪和干扰信号的实时合成,从而实现对高跳速射频通信信号的跟踪和干扰,用户可针对短波通信、超短波通信和微波通信扩展不同的模块,来实现在不同使用场景中的应用;经过测试,该射频通信干扰器的各项指标可满足使用要求,可进一步推广至电子对抗、无人机干扰等技术领域。In view of the shortcomings of traditional electronic jammers,such as complex system,large volume and high power consumption,A RF communication jammer based on FMC extended instrument(FXI)specification is designed.The FXI specification is based on the definition of FMC signal,aimed at the application of virtual instrument field,the structure of FXI module and the exclusive signal group of FXI interface are defined,which improves the function density of virtual instrument model,the design purposes of modularization,miniaturization and lightweight are realized.A spectrum analyzer module and a RF signal generator module are simultaneously integrated into the RF communication jammer.The hardware logic is used to implement the real-time tracking of RF signals and the real-time synthesis of interference signals,which realizes the interfere and tracking of the high-speed frequency hopping signals.With different users for shortwave communication,VHF communication and microwave communication,the jammer could be used to realize different scenarios.After testing,the parameters of the jammer meet the practical requirements.It can be further promoted to the other technical fields of electronic countermeasures and the UAV jamming.
