Propagation of Gaussian Beams Through a Modified von Karman Phase Screen
… statistics, utilizing the Fried parameter, inner scale and the outer scale. The scintillation index is analyzed as a function of the structure constant, phase screen location, the initial width of the Gaussian beam, etc. Similarly, the numerical simulations are extended using a pair of …

Measuring Optical Turbulence Parameters With A Three-aperture Receiver
… discussed along with a method to estimate the inner scale developed by Hill. The theory and minimization algorithm used to infer the atmospheric parameters are discussed. The main focus is on the analysis and collection of experimental data with a three-aperture receiver system. Intensity …

Design and Performance of a Communications System for a Low-Cost High Altitude Balloon Platform for Troposphere and Stratosphere Research
… is required to characterize turbulence to the inner-scale, or smaller, over paltitudes from 20 km to 35+ km.</p> <p>This thesis presents the development of a standard balloon bus, based on reliable COTS components, that includes radios operating in Ham/ISM frequencies with high-gain ground …

Fade Statistics For A Lasercom System And The Joint Pdf Of A Gamma-gamma Distributed Irradiance And Its Time Derivative
… used to infer the structure constant, Cn2, the inner scale and the outer scale from the optical measurements. The inferred parameters were used in calculations for the theoretical PDFs. It was found that fade predictions made by the gamma-gamma and lognormal distributions provide an upper and …
