Abstract :
In the paper, according to the ITU-R atmosphere model (ITU-R Document 3J/31-E, 2001) presented in 2001 by ITU-R, we study the Gaussian-beam wave scintillation index with altitude varying from weak fluctuation to strong fluctuation by applying a modification of the Rytov method. At the same time, we include the effect of a finite outer-scale in addition to the inner-scale. With a finite outer-scale, the scintillation index can be substantially lower in strong turbulence than that predicted by a model with an infinite outer-scale.
