摘要

摘要: 随着高功率微波技术的发展, 电子设备面临强电磁辐射攻击的威胁越来越严重, 对电子设备的防护加固提出了更高要求, 临近空间飞行器及其放电效应是目前较少考虑的环节, 且缺少相应的环境试验条件。文章提出了一种将临近空间气体环境与高功率微波电磁环境相结合的方法, 在柱形真空罐内壁布置吸波材料, 使用MW级S波段微波源及辐射聚焦系统在腔室中心形成强电磁辐射区, 以便开展相关辐照放电试验研究。针对脉冲微波强场监测, 通过光纤电场探头测量小信号连续波的方式进行等效传递, 中心场强最高超过2kV/cm。利用该试验装置可开展临近空间电子学系统在高功率微波辐照下的放电击穿研究, 对薄弱环节分析及防护加固提供帮助。

Abstract: With the development of high power microwave technology, the threat of strong electromagnetic radiation attacks on electronic devices is becoming more and more serious.Higher requirements are placed on the protection and reinforcement.Near-space vehicles and their discharge effect are less considered currently while lacking the corresponding test environmental conditions.A method of combining the near-space environment with the high power microwave is proposed.Experiment is conducted with strong electromagnetic zone in the cylindrical vacuum tank using the MW-level S-band microwave source and the radiation focusing system.The microwave source is adjustable in repetitive frequency 1-1000 Hz and pulse width 20 ns-20 μs.The atmospheric simulation chamber is adjustable under pressure 10^-3-10⁵ Pa and temperature-40 ℃to 60 ℃ with effective volume over 4 m³.The center field intensity measured by small signal transmission is over 2 kV/cm.The experiment technology can be used to carry out the discharge breakdown research of near-space electronic system under high power microwave, which is helpful for the weak link analysis and protection reinforcement.
