Abstract
The turbulence effect models derived with the Rytov theory method cannot be applied in the analysis of moderate-to-strong non-Kolmogorov turbulence. In this work, new expressions of the temporal power spectra of irradiance fluctuations are derived theoretically for optical waves propagating through moderate-to-strong non-Kolmogorov turbulence. They are developed under Andrews’ assumption that small-scale irradiance fluctuations are modulated by large-scale irradiance fluctuations of the optical wave. A wide range of turbulence strength is considered instead of a limited range for weak non-Kolmogorov turbulence. These expressions have general spectral power law values in the range 3 to 4 instead of the standard power law value of 11/3 for Kolmogorov turbulence. Calculations are performed to analyze turbulence strength and turbulence spectral power law’s variations on the final expressions.
