Through a Turbulent Atmosphere
The sta ti s ti cal di s tributi ons of th e a ngle of arrival, th e s pot location, the cross section, th e amp li . tude , th e carrier phase and the modulation phase of a lase r bea m tra ve rs ing an anisotropicaliy turbule nt at mos phere are de rived in terms of the s pace corre la tio n fun c tion of th e at mosph eri c index of refractio n a nd the windspeed. The Limit a ti o ns imposed...
متن کاملEfficient Optical Communication in a Turbulent Atmosphere
Given a transmitter that radiates an electromagnetic light field, we assume that the resulting field at the plane of the receiver aperture is log-normal with some coherence properties. Various representations of the field a r e discussed: aperture sampling, plane-wave decomposition, and Karhunen-Logve expansion. The statistical properties of the coefficients in these representations a r e inves...
متن کاملInfrared Scattering Observations in the Upper Atmosphere
Observations of sky emission and absorption in the far infrared (mean wavelength 120 /•) and, simultaneously, sky emission at wavelength 6 • have been made by P. Kuhn (ESSA): from the NASA CV-990 aircraft flying at 12-km altitude over the middle Pacific at latitudes 10ø-15øN. A lack of correlation between the nearand far-infrared data, especially during times of visible cirrus cloud cover above...
متن کاملInverse scattering problem in turbulent magnetic fluctuations
We apply a particular form of the inverse scattering theory to turbulent magnetic fluctuations in a plasma. In the present note we develop the theory, formulate the magnetic fluctuation problem in terms of its electrodynamic turbulent response function, and reduce it to the solution of a special form of the famous Gelfand–Levitan–Marchenko equation of quantum mechanical scattering theory. The l...
متن کاملPropagation of Partially Coherent Beam in Turbulent Atmosphere: A Review
Partially coherent beam is preferred in many applications, such as free-space optical communications, remote sensing, active laser radar systems, etc., due to its resistance to the deleterious effects of atmospheric turbulence. In this paper, after presenting a historical overview on propagation of optical beams in turbulent atmosphere, we describe the basic theory for treating the propagation ...
