摘要: 随着航空工业的发展,高强辐射场(HIRF)对机载电子设备的影响越来越大。因此开展对飞机上已经投入使用的机载电子设备屏蔽效能的测试与优化的研究具有重要的意义。基于RTCA/DO-160G和GJB 5185—2003建立HIRF的测试环境,在该电磁环境下对机载电子设备进行屏蔽效能的测试,分析了不同测试位置、不同入射面以及不同极化方式对屏蔽效能的影响。获得了机载通信设备的主要耦合通道,并针对不同耦合通道提出了通用性的优化方法。研究结果可为机载电子设备HIRF的测试以及屏蔽体的优化提供参考意见。

Abstract: With the development of aviation industry, High Intensity Radiation Field (HIRF) has more and more influence on airborne electronic equipment. Therefore, it is of great significance to test and optimize the shielding effectiveness of airborne electronic equipment. In this paper, the test environment of HIRF was established based on RTCA/DO-160G and GJB 5185-2003. The shielding effectiveness of airborne electronic equipment is tested under the electromagnetic environment, and the effects of different test positions and different incident surfaces on the shielding effectiveness were analyzed. The main coupling channel of airborne communication equipment is obtained. Finally, a general optimization method for different coupling channels is proposed. The results can provide references for the test of airborne electronic equipment HIRF and the optimization of shielding body.

Key words: airborne electronic equipment, high-intensity radiated fields, shield effectiveness, electromagnetic coupling, shield optimization
