Characterizing the propagation path in moderate to strong optical turbulence

Abstract

In February 2005 a joint atmospheric propagation experiment was conducted between the Australian Defence Science and Technology Organisation and the University of Central Florida. A Gaussian beam was propagated along a horizontal $1500\text{\hspace{0.17em} m}$ path near the ground. Scintillation was measured simultaneously at three receivers of diameters 1, 5, and $13\text{\hspace{0.17em} mm}$. Scintillation theory combined with a numerical scheme was used to infer the structure constant $C_n^2$, the inner scale $l_0$, and the outer scale $L_0$ from the optical measurements. At the same time, $C_n^2$ measurements were taken by a commercial scintillometer, set up parallel to the optical path. The $C_n^2$ values from the inferred scheme and the commercial scintillometer predict the same behavior, but the inferred scheme consistently gives slightly smaller $C_n^2$ values.
