An Experimental Study of the Signal to Noise Ratio of Radiated Emissions in the Presence of Thermal Noise in a Reverberation Chamber

In this paper the phenomenon of thermal noise present in a reverberation chamber and received through an antenna within the chamber is reviewed. The consequences of the thermal noise are described in terms of the observed signal to noise ratio of a signal radiated by an equipment-under-test placed at a number of positions in the chamber. It is shown that the observed signal-to-noise ratio is dependent on both the position of the equipment-under-test within the chamber and on the stirrer position.
