Investigation of the distribution of the random LOS component in a reverberation chamber

In the previous measurement uncertainty work by Kildal, et al. (2012), the random line-of-sight (LOS) component in a reverberation chamber (RC) was assumed to be Gaussian distributed without quantitative justification. In the present paper, we apply goodness-of-fit (GOF) test to the measured LOS component samples to check its Gaussianity. It is shown that the Gaussianity hypothesis of the distribution of the random LOS component is accepted at most of the frequencies, which justifies the Gaussian LOS component assumption.
