Abstract

The recently developed IK distribution and its connection with other distributions is examined in the context of optical waves scattered by a turbulent medium. In particular, it is shown how the IK distribution, K distribution, and homodyned K distribution all evolve as marginal density functions from compound or doubly stochastic Gaussian optical fields. In this setting the genesis of the IK distribution is very similar to that of the homodyned K distribution, and there is one special case (α = 1) in which the two distributions are identical. Also, both the homodyned K and the IK distribution are shown to reduce to the K distribution in strong-turbulence regimes. The IK distribution is further examined as a model for the irradiance when the distribution parameter α is restricted to half-integer values, leading to simpler forms of the distribution. The special case of the IK distribution corresponding to α = 1/2 shows a particularly good fit with experimental data over a wide range of conditions of atmospheric turbulence.
