Paper Abstract

Scintillations-based optical techniques for the measurement of the atmospheric transverse average wind velocity are re-examined. Three different methods for the processing of the resultant time-lagged covariance function are compared to in-situ anemometer measurements. A correlation index of 0.89-0.95 is obtained between the optical and anemometer results and it tends to increasing with the measurement time constant. Some degradation in the accuracy of the optical methods is observed when the spacing between the detectors is either much smaller or much larger than the Fresnel zone [AL]1/2.
