Abstract

The correlation coefficient of the scintillations of two waves at different wavelengths propagating simulta¬neously in the same turbulent atmosphere over the same path was measured. The results show that at weak turbulence the correlation is higher than predicted if the Kolmogorov spectrum is used. With increasing turbulence, it was found that correlation is lost much faster than predicted by MSP approximation if a constant shape turbulence spectrum is used. The experimental results can be partially accounted for if a dependence of the inner scale size parameter on turbulence strength is assumed. The experimental results indicate that with increasing turbulence strength the relative weight of the small size turbulent eddies increases.
