摘要在评定电磁混响室内的场均匀性基础上,进一步测试了机械搅拌桨的扰动以及不同接收天线位置对所模拟复杂无线信道的均方根时延展宽波动性的影响。证明了该新建电磁混响室的场均匀性指标优于2.5 dB,且定量评价了均方根时延展宽波动范围。对两类指标差异性的分析则进一步明确了场均匀性与均方根时延展宽波动性在不同应用中的作用。

Abstract：Based on the validation of field uniformity, fluctuation of root-mean-square (RMS) delay simulated in reverberation chamber is also investigated, by considering the disturbance introduced by mechanical stirring and positions of receiving antenna. The field uniformity of reverberation chamber is proved to be better than 2.5dB, and the range of RMS delay is also quantitatively evaluated. The differences between the field uniformity and the fluctuation are analyzed for indicating the different roles that they played in some applications.

Key words： metrology reverberation chamber field uniformity RMS delay simulation
