As was shown previously, the numerical solutions of the equation governing the propagation of the fourth-order statistical moment in a random medium and its solutions based on the two-scale expansion procedure are in good qualitative and quantitative agreement. In the present work, we apply the propagator formulation of the problem together with a directional source initial condition to obtain a computable two-scale algorithm for the intensity correlation characteristics of finite aperture radiation. Computations of these expressions show different behavior of the intensity correlation characteristics from those of plane and spherical waves.
