Abstract

Parameters characterizing the atmospheric turbulence in a 16 km maritime optical link were measured over a 6 month period in 2007, on a continuous basis as conditions allowed. Both the scintillation index and the atmospheric structure constant were found to have a strong dependence on the air - water temperature difference. Temporal-frequency spectra were also generated from the received intensity fluctuations. In this paper the frequency components of the laser irradiance are studied in order to ascertain the degree of correlation with prevailing meteorological conditions. In addition, the high frequency behavior of the power spectra is documented and shows an extensive range of values for the power-law scaling index.
