Choice of the Model of Atmospheric Turbulence

Applied Optics, 1972
The concept of equivalent models of turbulence is introduced in order to investigate how the theoretical behavior of the structure function of an electromagnetic wave propagating in a given turbulent medium depends on the turbulence model. It is shown that equivalent models may give rise to substantially different structure functions of a wave ...

The Structure of Atmospheric Turbulence

Theory of Probability & Its Applications, 1958
Theoretical and experimental data are given for the statistical characteristics of random fields of wind velocity and turbulent fluctuations of temperature in the lowest layer of the atmosphere. Fluctuations are considered at one and two space time points.

Atmospheric turbulence mitigation based on turbulence extraction

2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016
A video taken under the influence of atmospheric turbulence suffers from serious distortion caused by the variation of optical refractive index. In order to reduce geometric distortion and time-space-varying blur, and recover both coarse structure and fine details, a novel turbulence extraction based approach for recovering a latent image from an ...

Propagation of Sound in a Turbulent Atmosphere

The Journal of the Acoustical Society of America, 1970
Applying a perturbation technique to the correct form of the equation for the acoustic pressure field in a viscous turbulent atmosphere yields the power spectra for the amplitude and phase fluctuations of a propagating plane wave. The development includes the effects of absorption and removes the restrictions on wavenumber that previously prevented ...

Atmospheric turbulence

Quarterly Journal of the Royal Meteorological Society, 1948
AbstractEvidence which has accumulated shows that the classical theory of atmospheric turbulence which assumes thatKthe coefficient of eddy diffusion is constant with height is inadequate to explain the observed variations of wind and temperature with height.

Turbulence of the upper atmosphere and isoplanatism

Applied Optics, 1979
We report the results of 1,049 measurements of the vertical profile of optical turbulence as recorded by a scintillometer above a site at White Sands Missile Range. The distributional law for these measurements is shown to be approximately log normal and examples of monthly to hourly variations in profile structure are presented.

Interactive Atmospheric Turbulence Mitigation

2016 International Conference on Digital Image Computing: Techniques and Applications (DICTA), 2016
Surveillance imagery acquired at long distances is frequently degraded by atmospheric turbulence, causing it to be blurry and distorted. We introduce an interactive method for atmospheric turbulence mitigation of video sequences. Our method allows the user to input crucial information about the imaging conditions, hence bypassing many of the ...

In-flight investigations of atmospheric turbulence

Aerospace Science and Technology, 1998
Abstract One of the key technologies in aeronautics offering substantial improvements in the fields of economy and ecology is the laminar flow technology. The sensitivity of the laminar boundary layer flow over aerodynamically smooth surfaces to the effects of disturbances like noise, vibration and insect contamination as well as the atmospheric ...
