Influence of the random refraction of radio waves in the corona on the properties of solar noise storms

Scattering of radio waves on irregularities in the coronal electron density is inevitably accompanied by variations of scattered signal intensity. According to the probability theory, the scattered signal intensity distribution is described by an exponential law. The empirical intensity distribution in the majority of the observed noise storms is also adequately described by an exponential law, and this fact counts in favor of the hypothesis that the burst component of noise storms is formed as a result of the scattering of the radio radiation from quasi-stable point sources on coronal irregularities.
