Phase fluctuations in a turbulent medium.
General relationships are shown relating the log-amplitude and the phase fluctuations to the Rytov geometric optical solution for the phase fluctuation under the assumption of normal distribution for the log-amplitude and the phase fluctuations. In the weak fluctuation region, this general relationship reduces to the Rytov solution. In the strong fluctuation region, the phase correlation function is shown to approach the Rytov geometric optical solution.
