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   m path near the ground. Scintillation was measured simultaneously at three receivers of diameters 1, 5, and 13   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.
