Estimating K-Factor and Time Spread Parameters From a Transient Response of a Pulse Modulated Sine Wave in Reverberation Chamber

A statistical model based on the power profile of the transient response of a reverberation chamber is proposed in order to extract
K
-factor and different time parameters.
K
-factor is described as a function of time moments and the normalized level of the power of the signal envelope. Analytical relations for the mean delay spread τ
_μ
and the root mean square delay spread τ
_rms
are computed. The average absorbing cross section of the loading materials is also estimated with regard to
K
-factor. Simulations and measurements validate and show the utility of this method.
