Account of an optical beam spreading caused by the turbulence for a propagation problem of the partially coherent radiation in inhomogeneous absorbing media

The propagation problem for a partially coherent wave field in inhomogeneou s random media is considered in this work. The influence of the refraction, the inhomogeneity of gain (absorbing) medium properties and refraction par ameter fluctuations on target radiation characteristics are taken into cons ideration. On the basis of the solution of the equation for the second orde r coherence function the ray-tracing technique makes an algorithm of the ac count of turbulence and medium inhomogeneity for arbitrary initial coherenc e.
