摘要：
The statistical description of atmospheric turbulence and laser propagation through the atmosphere is complicated by global intermittency, the slow variations in space and time of the basic turbulence parameters. The effects of global intermittency of atmospheric turbulence on the mutual coherence function and the irradiance spectrum are investigated with numerical simulation. The effects of global intermittency are negligible when the path length is of the order of 10 correlation scales of global intermittency. This condition is readily satisfied for typical atmospheric parameters. The higher moments of irradiance appear to be more sensitive to the effects of global intermittency.
