Abstract

A method of measuring the atmospheric turbulence based on the arrival angle fluctuation of a focused laser beam backscattering is numericallys stimulated. By the paraxial scalar wave equation and a fractal phase-screen algorithm we propose the simulation model for the focused laser beam propagating along a fold path. With a constant Fried length, we separately analyze the arrival angle fluctuation variance's statistical characteristics of the focused laser beam backscattering and the fixed point-source as reference beacon, and obtain the relatively high correlation between them. Moreover, we change the propagation distance; analyze the degree of similarity between them. The simulated results are verified by experimental results.
