国内外机载设备电磁环境验证标准分析
Difference Analysis of Airborne Equipment Electromagnetic
Environment Certification Standards in China and Abroad
摘要 RTCA/DO-160G和GJB 151A/152A-97都涉及了电磁环境验证,高强度辐射场(HIRF)试验项目是重点的验证项目,重点比较分析这两个标准对该项目在测试条件、测试对象及测试方法的差异,得出对于飞机机载设备的传导敏感度和辐射敏感度的试验,采用GJB 151A/152A可能会出现要求过高的情况,而采用DO-160G则更加方便灵活。

Abstract The standard RTCA/DO-160G, American Environmental Conditions and Test
Procedures for Airborne Equipment, and China national military standard GJB 151A/
152A-97, Measurement of Electromagnetic Emission and Susceptibility for Military
Equipment and Subsystems, have large differences in electromagnetic environment
certification. The tests relevant to High Intensity Radiated Field (HIRF) are emphasized.
Both standards include test items associated with HIRF. The test conditions, objects
and methods in these two standards are compared. Finally, the result shows that the
test requirements in GJB 151A/152A-97 may be much stricter, and the requirements in
RTCA/DO-160G is more flexible and convenience.
