中文摘要:
      针对北斗接收机易受高功率微波干扰问题,采用圆极化贴片天线为辐照对象,基于CST(computer simulation technology)微波工作室和ADS(advanced design system)2种软件的联合仿真方法,将天线辐照产生的感应电动势注入接收机射频前端电路,并设置节点监测电路参数。仿真实验分析了窄带和超宽带高功率微波对导航接收机辐照的前门耦合过程,结果表明,超宽带电磁脉冲可以引起北斗接收机二级低噪声放大器晶体管烧毁,窄带电磁脉冲会造成前端限幅二极管击穿,造成导航系统无法工作。研究确定了接收机电路的易损部件,为北斗导航接收机的电磁防护设计提供了依据,研究方法也可为其他电磁脉冲前门耦合效应仿真实验提供参考。
English Summary:
      Aiming at the problem that BeiDou receiver is vulnerable to interference caused by high power microwave, the circularly polarized patch antenna is used as the irradiation target, and the induced electromotive force generated by the antenna irradiation is injected into the RF front-end of the receiver based on the co-simulation of CST and ADS, the monitoring nodes are set to record circuit parameters. The front-door coupling process of narrow-band and ultra-wideband high-power microwave irradiation to the navigation receiver is analyzed through the simulation.The results show that the ultra-wideband electromagnetic pulse can cause the secondary low-noise amplifier transistor of the Beidou receiver to burn out, and the narrow-band electromagnetic pulse will cause the front-end limiting diode to break down,resulting the navigation system being unable to work. The vulnerable parts of the receiver circuit were determined and the basis for the electromagnetic protection design of the Beidou navigation receiver was provided by the study, the research method can also be used as the reference for other electromagnetic pulse front door coupling effect simulation experiments.
