Abstract :
Disturbance, caused by a solar flare, is accompanied with the radio emission of falling down frequency, affects the biosphere and influences on operation quality of many devices of surface and space equipment. The presence of heterogeneity on the way of radio waves results in the origin of interference and scintillation of observed radio emission. Comparison of analytical description of scintillation with the results of spectral observations from remote points showed that the formation of fiber-structures with intermediate speed of drift and the wide-band pulsations of solar flare radio emission is satisfactorily explained by multibeam propagation of radio waves through coronal plasma.
