FOREWORD

1. This standard is approved for use by all Departments and Agencies of the Department of

Defense.

2. The stated interface requirements are considered necessary to provide reasonable

confidence that a particular subsystem or equipment complying with these requirements will

function within their designated design tolerances when operating in their intended

electromagnetic environment (EME). The procuring activity should consider tailoring the

individual requirements to be more or less severe based on the design features of the intended

platform and its mission in concert with personnel knowledgeable about electromagnetic

compatibility (EMC) issues affecting platform integration.

3. An appendix is included which provides the rationale and background for each requirement

and verification section.

4. A committee consisting of representatives of the Army, Air Force, Navy, other DoD

agencies, and industry prepared this document.

5. Comments, suggestions, or questions on this document should be addressed to

AFLCMC/EZSS, Bldg 28, 2145 Monahan Way, Wright-Patterson AFB OH 45433-7017 or

emailed to AFLCMC/EN_EZ_Engineering.Standards@us.af.mil. Since contact information can

摘要：

MIL-STD-461G-2015 是美军电磁兼容性和电磁干扰控制的核心标准规范，适用于军用系统和设备在采购与鉴定中的电磁发射与敏感度测试。该标准明确了从30 Hz至40 GHz频率范围内的传导与辐射发射及敏感度限值，并规定了详细的测试配置、环境条件和验收准则，旨在确保军用电子、电气及机电设备在复杂电磁环境中能够互操作且不发生性能退化。MIL-STD-461G 作为当前广泛引用的版本，替代了 MIL-STD-461F，并引入了对数字设备、宽带噪声以及更严格敏感度要求的更新，是国防承包商、军工科研
