The paper presents a tool for numerical simulation of the backscatter enhancement effect associated with double-pass propagation of laser radiation passing through an anisotropic non-Kolmogorov turbulence. It is shown that for variety of power-law exponents of refractive-index fluctuations, all other conditions being equal, the value of the enhancement factor also changes: it increases when the fluctuation spectrum becomes more and more low-frequency. For the anisotropic medium, the two-dimensional distribution of the enhancement factor allows remotely determining the spatial orientation of anisotropic inhomogeneities in a randomly inhomogeneous medium.
