Research on port electromagnetic pulse protection method for HF communication equipment

针对传统的短波通信设备端口电磁脉冲防护方法防护效果差的问题,本文对短波通信设备端口电磁脉冲防护方法进行设计。在分析电磁脉冲原理的基础上,采用换算公式,得到驻波比、反射系数与回波损耗系数间的换算,通过改变阻抗改变功率传输,对短波通信设备端口进行基础保护。并按照磁偶极子天线作近似分析对电磁脉冲的破坏机理进行分析,在此基础上,对短波通信设备端口进行多级防护,以此完成对短波通信设备端口的防护。同时,为了保证此次设计方法的有效性,设置实验环境,进行实验对比。实验对比结果表明,此次设计的对短波通信设备端口进行多级防护方法比传统的防护方法防护效果好,具有一定的实际应用意义。

Aiming at the poor protection effect of the traditional port electromagnetic pulse protection method for shortwave communication equipment,this paper designs the port electromagnetic pulse protection method for short-wave communication equipment.Based on the analysis of the principle of electromagnetic pulse,the conversion formula is used to get the conversion between standing wave ratio,reflection coefficient and echo loss coefficient.By changing impedance to change power transmission,the basic protection of HF communication equipment ports is carried out.According to the approximate analysis of the magnetic dipole antenna,the damage mechanism of electromagnetic pulse is analyzed.On this basis,the ports of HF communication equipment are multi-level protected to complete the protection of the ports of HF communication equipment.At the same time,in order to ensure the effectiveness of the design method,the experimental environment is set up and the experimental comparison is carried out.The experimental comparison results show that the multi-level protection method designed for HF communication equipment ports has better protection effect than the traditional protection method,and has certain practical application significance.
