摘　　要：从检测系统和检测环境方面,分析导致辐射发射(RE)测试中底噪异常问题的可能原因、验证方法和不同验证结果所对应的验证结论。以某次汽车零部件辐射发射测试时遇到的底噪异常问题为例,说明异常问题的实际排查验证过程,为相似问题的验证排查提供参考思路。Analyze the possible causes,validation methods,and validation conclusions for the different verification results that can lead to abnormal noise underfloor issues in radiation emission(RE)tests,both in terms of the detection system and the test environment.Take an example of an abnormal background noise problem encountered during a radiation emission test of a car component,explain the actual troubleshooting verification process for the abnormal problem,and provide a reference point for the verification and troubleshooting of similar problems.

关 键 词：电磁兼容 辐射发射 底噪
