Probability Density Function of the Quality Factor for Reverberation Chambers Operating With Hybrid Stirring Including Frequency Stirring

摘要

In this letter, we deal with the probability density function (PDF) for the quality factor of reverberation chambers operating with combined mechanical and frequency stirring techniques. It will be shown the PDF of step-tuned and mode-stirred reverberation chambers (RCs), respectively, where the mechanical and frequency stirring are combined, and how it is affected by the width of the frequency sweep. The results for source-stirred RCs, where the frequency stirring is combined with source stirring, are implicitly obtained as well. By the results, possible effects on the measurements due to combinations of stirring techniques, including the frequency stirring, are also shown.
