Abstract : Starting from the parabolic equation for a wave propagating in a random medium, the equation for the general mutual coherence function is derived, and a solution is obtained for the same using a perturbation technique, assuming the Kolmogorov spectrum for the fluctuations of the refractive index. It is shown that the solution so obtained is exact when the coherence function is evaluated at a single point and at the same time, but at two different frequencies. Using this exact solution for the two frequency correlation function, the propagation characteristics of a plane wave Gaussian and rectangular pulses are studied at mm and optical wavelengths.
