摘　　要：研究了电磁脉冲激励混响室内电磁波传播规律,通过仿真建模和实验两方面对脉冲激励混响室测试区域内电磁场均匀性进行了研究。提出了混响室时域均匀性的概念及其计算方法,并利用此方法计算了仿真和实验结果。结果表明:脉冲激励混响室内电磁环境无论在时域上还是频域上,均满足国际标准规定的均匀性要求;在一定空间内,混响室内也可以形成统计平均的脉冲场电磁环境;在混响室内进行电磁脉冲场的电磁敏感度测试是可行的。The field uniformity of electromagnetic in a pulse excited reverberation chamber was investigated in simulations and experiments.The definition and calculation method were proposed and the results of both aspects were analyzed.The results showed that the field uniformity of pulse excited reverberation chamber is fulfilled with the requirement of IEC standard both in time and frequency domains.The fact that the statistical uniformity field can be built in pulse excited reverberation chamber suggests that the susceptive experiments under electromagnetic pulse field can be performed in reverberation chamber.
