The statistical structure of atmospheric noise arriving at the antenna is assumed as follows, that is, atmospheric noise consists of a series of pulses, in which the distribution of peak voltage of the pulses is given by the log-normal distribution and the pulses have a given duration of carrier waves modulated by a rectangular form. On receiving the atmospheric noise assumed, the amplitude probability distributions of the envelope voltage at the output of the receiver have been evaluated for the given receiver response. The calculated amplitude probability distributions showed various forms dependent on the noise conditions, that is, density and strength in the assumed atmospheric noise. The comparison between the calculated- and the measured-amplitude probability distributions showed the interesting fits in the frequency range of 50 kc to 500 kc. The theory used in deriving the amplitude probability distributions and the results obtained will be shown in detail and some examples of fitting between the calculated- and the measured amplitude probability distributions will be shown in this paper.
