摘　　要：本征电磁混响室既继承了混响室的优点,又能克服机械搅拌混响室效率低、电子搅拌混响室不能进行辐射发射测试和低频性能较差的问题,是大型装备系统/设备级EMC试验场地最有希望的研究方向之一。根据本征电磁混响室的基本结构和工作原理,分析了本征电磁混响室在理论研究、结构设计和测试应用中需要解决的本征电磁混响室电磁场的模式理论与统计分布规律、腔体几何外形与散射器的结构优化、性能指标分析与评估、数值仿真、测试应用方法与流程等方面的关键技术及其研究思路和方法,为本征电磁混响室技术的研究提供一定的参考和借鉴。The technology of the intrinsic reverberation chamber （IRC） for EMC test is presented. The advantages of IRC, which costs less test time than the conventional reverberation chamber with a mode stirrer and can be used for radiation emission test, make it possible to be one of the most promising research direction for EMC test field of large-scale equipment. According to the basic structure and operating principle of IRC, the key technologies of the IRC are analyzed, including mode theory and statistical distribution of the electromagnetic field in the IRC, configuration optimizing of chamber geometry and wave diffusers, analyzing and evaluating the characteristic parameters of IRC, numerical simulations, methods and proce-dures for EMC test with IRC. And the research ideas and methods of such key technologies are investigated, which could provide references for the research of IRC.
