Protection design of BD/GPS navigation system to resist high power microwave

  • 摘要: 为提升北斗/GPS导航接收系统抗高功率微波的防护效能,采用场路协同仿真设计的方法,分析了北斗/GPS天线在高功率微波辐照下的响应特性,仿真得到天线端口的耦合电压量值。为实现对高功率微波的防护,设计两级防护电路,通过构建稳态电路和瞬态电路模型,对插入损耗和泄漏电压进行仿真分析,并对防护电路进行了加工。测试结果表明:防护电路在2 kW的窄带高功率微波注入下,泄漏功率小于0.5 W;在1411 V的超宽谱高功率微波注入下,泄漏电压小于12 V,可实现对高功率微波的有效抑制。同时将防护电路装配到北斗/GPS导航天线内,导航系统可正常工作。
