Correlation between scintillation of laser beam and wind noise

Abstract

The wind noise fluctuates randomly owing to the temporal changes of wind speed. The scintillation of laser beam results from temporal and spatial changes in atmospheric turbulence and/or pressure. In this paper, the power spectral density function (PSDF) as statistical characteristics for the wind noise is first discussed by applying the theoretical PSDF of atmospheric turbulence to this wind noise. Next, the correlation between the scintillation of laser beam and the wind noise is studied from the experimental viewpoint.
