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。Abstract: To enhance the protective effectiveness of the Beidou Navigation Satellite System (BDS) and the Global Positioning System (GPS) against high-power microwave, we adopted the method of field-circuit collaborative simulation design to analyze the response characteristics of the BDS/GPS antenna under high-power microwave irradiation. The coupling voltage was obtained by simulation. To achieve protection against high-power microwave, a two-stage protection circuit was designed. By constructing steady-state and transient circuit models, the insertion loss and leakage voltage were analyzed according to simulation, and the circuit was processed. The test results show that the leakage power of the protective circuit was less than 0.5 W under HPM-NS injection of 2 kW, the leakage voltage was less than 12 V under HPM-UWS injection of 1 411 V, and this proposed circuit structure can achieve effective suppression of high-power microwave. The protection circuit was assembled into the BDS/GPS antenna, and the test results show that the navigation systems can operate normally. -
