On the Time Domain Error Caused By the Frequency Domain Sampling Rate in a Reverberation Chamber

The time domain (TD) response of a reverberation chamber (RC) can be obtained from the inverse Fourier transform of the measured S-parameters in the frequency domain (FD). In the measurement, the FD sampling rate should be high enough; otherwise, the measured S-parameters will be uncorrelated, and the inverted TD response will be meaningless. We investigate the TD error caused by the sampling rate in the FD based on the measured S-parameters; from a statistical perspective, the empirical cumulative distribution functions of the TD errors for different FD sampling rates are also given.
