Abstract:
Observations at AMOS and elsewhere suggest that turbulence is sometimes non-isotropic and non-Kolmogorov in nature. Such turbulence can produce different jitter, wavefront error, and scintillation than expected from isotropic Kolmogorov turbulence. These differences can impact the design of sensor systems that must see through this atypical turbulence. Quantitative definitions are provided for anisotropic turbulence and non-Kolmogorov turbulence. Using previously developed analyses and with extensive simulations for a plane wave, results are presented that parametrically show how scintillation differs from that of standard Kolmogorov turbulence, under a variety of conditions.
