Abstract

The statistical distribution of experimentally obtained higher oreder moments of optical scintillations probability density is studied. It is shown that this distribution is strongly dependent on the size of the data sample. At reasonable and practical sample sizes the correct estimation of the theoretical value is improbable. In practice, the sample size is limited by the scintillations bandwidth and the length of time in which the turbulence is stationary. At practically available sample sizes the region of the most probable values of the estimated higher order moment is almost independent of the scintillation PDF. The distinction between the candidate PDF's is almost impossible at reasonable sample sizes. These conclusions are derived analitically and demonstrated by simulation techniques.
