Frequency Spectrum of Optical Waves Propagating in a Moving Turbulent Atmosphere.
Abstract
The authors have calculated the frequency spectrum of plane waves and beams propagating in a moving turbulent atmosphere. Both the case when the atmosphere moves with a constant wind and the case when the wind velocity is distributed according to a gaussian centered about some average velocity is considered. The results indicate that for small propagation distances, the frequency spectrum behaves as omega sup -8/3 for large frequency, omega; for large propagation distances, the spectrum is broadened with increasing distance-with the broadening dependent upon the beam parameters and the wind velocity.
