Abstract
The influence of deviations from the Kolmogorov–Obukhov model in the spectra of refractive index fluctuations in a supersonic air flow on transmitted optical radiation is studied. Statistical moments of a field are analytically estimated; laser radiation propagation through a high-speed air flow generated during flowing around an aircraft is simulated. The estimates of the coherence length and the relative dispersion of optical wave intensity fluctuations are compared. Consideration of deviations from the model of developed turbulence is shown to cause significant (several times) changes in the estimates of laser beam characteristics at a distance of several hundred meters. The results can be used to estimate radiation distortions under the turbulence effect in an optically active layer near the surface of supersonic aircraft on location and communication routes.
期刊介绍：
Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
