Results are described of a theoretical and experimental investigation on the statistics of amplitude fluctuations of an atmospherically degraded laser beam. The research is aimed at deducing information on the impinging signal from the statistics of the revealed signal, that is distorted by the non-linearity of the detecting apparatus. Application to a set of experimental data, measured by us after 4.5 km atmospheric propagation of a laser beam, at about 20 height over ground, allows us to exclude a Rice-Nakagami distribution for the amplitude of the impinging signal, in favour of a log-normal distribution.

Abstract
Results are described of a theoretical and experimental investigation on the statistics of amplitude fluctuations of an atmospherically degraded laser beam. The research is aimed at deducing information on the impinging signal from the statistics of the revealed signal, that is distorted by the non-linearity of the detecting apparatus. Application to a set of experimental data, measured by us after 4.5 km atmospheric propagation of a laser beam, at about 20 height over ground, allows us to exclude a Rice-Nakagami distribution for the amplitude of the impinging signal, in favour of a log-normal distribution.
