Abstract:On the basis of Kolmogorov's theorem, the physical meanings of beams' correlation function on received plane are extended. Approximate formula of channels' across correlation coefficient is deduced from multiple beams through atmosphere. And the scintillation variance of multiple beams is induced as well. The result shows that when the channels are close to one another, the correlation coefficient increases, and so the scintillation variance does. When the channels completely combine, the scintillation variance of multiple channels is not difference from that of one channel.
Keywords:correlation coefficient  scintillation variance  logarithm amplitude fluctuation  atmospheric turbulence
