Abstract

An inhomogeneous turbulent medium is characterized by a refractive index spectrum that varies from point to point. The mutual coherence function (MCF) is used to analyze the distortion that electromagnetic waves suffer when they propagate through such a medium. In this paper, we analyze the MCF in two dimensions for an incoherent line source. We show that the MCF consists of delta and non-delta components and derive the differential equations that each component must satisfy. Finally, we present results obtained by a numerical solution of these differential equations.
