摘　　要：基于星载大容量固态存储器的EMI辐射测试结果,对其电磁不兼容状态进行了EMC分析与整改。依据GJB151A-1997,星载大容量固态存储器需要满足RE102电场辐射要求,为了使RE102超标严重的星载大容量固态存储器满足标准要求,首先,结合星载大容量固态存储器的工作原理,依据电磁屏蔽理论及电磁辐射理论,对RE102的测试结果进行了分析。其次,确定了辐射超标的主要原因为互连线缆的电磁辐射,并进一步分析了电磁辐射的激励源产生方式。最后,依据分析结果提出了相应的整改方案并进行了整改。结果表明,采用EMC屏蔽和滤波措施后,EMI发射衰减大于30dB,星载大容量固态存储器的EMI辐射测试结果满足RE102技术指标要求。Based on EMI radiation test results of high-capacity solid state reorder on the spacecraft , its electromagnet-ic not compatible status is analyzed and corrected.High-capacity solid state reorder on the spacecraft needs to meet electromagnetic radiation requirements, such as RE102.In the electromagnetic compatibility standard test, RE102 is seriously overweight.Firstly, combined with high-capacity solid state reorder’s works, based on the theory of electro-magnetic shielding and electromagnetic radiation theory, the test results of the RE102 is analyzed.Secondly, the main reason for the overweight of electromagnetic radiation in interconnect cables is confirmed .And the excitation ra-diation source to generate electromagnetic is further analyzed.Finally, the rectification plan is accordingly proposed. The results show that, after using EMC shielding and filtering measures, EMI emission attenuation is greater than 30dB, high-capacity solid state reorder’s EMI radiation test results meet the technical requirements of RE102.
