Performance Estimation and System Modeling for Refractive Index Structure Constant Cn2

Abstract

Random turbulence fluctuations cause continuous fluctuations in the refractive index, which will eliminate the coherence of light waves. Research into atmospheric turbulence is in fact an investigation of the atmospheric refractive index. The constant of atmospheric structure represents a significant parameter that is indicative of the strength of the atmospheric turbulence. In the present study, the performance of some standard models, such as Hufnagel-Valley 5/7, Submission Laser Communication, Critical Laser Enhancing Atmospheric Research, and the Air Force Geophysics Laboratory and Air Force Maui Optical Station, for estimating the C2n, was evaluated with a focus on location assessment. The bias and RMSE were found to be significantly less than 1 £ 10¡14 m¡2/3 for Holloman and Hefei cities, and s is basically less than 0.25 £ 10¡14m¡2/3 for Holloman and Hefei cities. During day and night transitions, Rxy, is well for Holloman, Louisiana, and Hefei cities. Using standard models, we discovered a satisfactory match between the measured (observed) and estimated values for tropical locations.
