摘　　要：依据IEC标准中的调谐模式混响室确认方法,对新建造的混响室进行场均匀性校准,设计了基于LabVIEW的自动校准软件。测试结果表明,该混响室的工作区域场均匀性小于3 dB,满足了标准规定的容差要求。同时,核心区域比外围区域均匀性好。对比搅拌桨"同步"转动和"异步"转动,两种转动方式场均匀性结果较一致。According to the reverberation chamber validation for mode-tuned operation of IEC,the field uniformity of the newly constructed reverberation chamber is calibrated.Automated test software based on LabVIEW is designed.The test results indicate that the field uniformity of working area is less than 3 dB,and it can meet the standard requirement.Meanwhile,the field uniformity of core area is better than the peripheral area.Compared paddles ＂synchronous＂ rotation with ＂asynchronous＂ rotation,the results of the field uniformity are consistent.
