Propagation of Narrow Bandwidth Wavelength Radiation Through the Atmosphere

Abstract

The analytical theories that describe the irradiance profile and scintillation index for a Gaussian beam propagating through atmospheric turbulence are reviewed. Both horizontal and slant propagation paths are considered. A turbulence strength C(n)2 model, with daytime and nighttime versions, is described that is generally consistent with our understand of White Sands Missile Range (WSMR), NM conditions. The expressions and turbulence strength model are used to generate a set of curves that show received beam sizes and scintillation indices as a function of the initial beam size (radius), the wavelength, the path elevation angle, and the propagation distance.
