摘　　要：针对武器系统中的半导体桥火工品无法满足在连续电磁波环境中使用要求的问题,采用匹配滤波器的方式进行了半导体桥火工品的电磁防护设计,并利用实验室建立的连续电磁波环境模拟系统对火工品进行了辐照研究。结果表明,滤波器对半导体桥火工品在电磁场特别是高频电磁场中耦合的能量有明显衰减效果,使其满足规定的安全裕度要求,显著提升了半导体桥火工品及武器系统在高频电磁场中的安全性和可靠性。In view of the situation that that the semiconductor bridge initiators in the weapon system cannot meet the requirements for use in the continuous electromagnetic wave environment,the electromagnetic protection design of the semiconductor bridge initiators was proposed by using matched filters,and the electromagnetic radiation experiment of continuous electromagnetic wave environment simulation established by the laboratory was carried out.The results show that the filter has a significant attenuation effect on the energy of the semiconductor bridge initiators coupled in the electromagnetic field,especially the high-frequency electromagnetic field,so that it meets the specified safety margin requirements,and significantly improves the safety and reliability of the semiconductor bridge initiators and weapon systems in electromagnetic fields.
