摘　　要：给出了混响室测试系统的设计方法和基本性能的预测分析。根据设计建造了混响室,并且采用自动化测试软件完成了校准测试,分析了电场均匀性、品质因数等性能指标。测试表明建造的混响室性能完全符合测试标准的规定,多次测量重复性很好。最低可用频率200MHz,电场均匀性小于3dB。可以用来进行电磁兼容辐射发射和辐射抗扰度测试。The design method of the reverberation chamber and the prediction analysis of its performance were described in detail. A real reverberation chamber was constructed according to the design. The performance of the reverberation chamber was calibrated strictly using the automotive measurement software. Some parameters such as field uniformity and quality factor were analyzed sufficiently. Measurement data indicate that the performance of the proposed reverberation chamber conforms to the IEC standard and show excellent repeatability in this chamber. The lowest usable frequency is 200MHz and the field uniformity is less than 3dB. This reverberation chamber can be used to evaluate the radiated emission or susceptibility of equipments under test.
