Wave propagation through a tropospheric layer of anisotropic turbulence was studied by comparing both the wave theory microwave optics approach, applicable to homogeneous layers, and the single scattering first Born approximation approach applicable to homogeneous turbulence. The first order correspondence of wave theory and single scattering theory results for the homogeneous layer at least for the normal incidence indicated that a single scattering theory approach can be expected to give valid approximations of the propagation effects produced by nearly homogeneous layers. The single scattering theory formulation of turbulent layer problem is more complex due to the mathematics necessary to describe the turbulence the single scattering concepts should be just as valid as for the homogeneous layer. The diffracting screen approach offered a convenient means of interpretation of the propagation effects produced by a turbulent layer.
