  Computer simulations of radio energy transfer in the ionospheric layer with
random small-scale irregularities for the case of a point ground-based source
and total reflection have been carried out using specially designed algorithm
based on Monte Carlo method ideas. The model demonstrates redistribution of the
reflected radiation power on the Earth's surface caused by multiple scattering
process. The obtained data can serve as illustration of the effect of anomalous
attenuation of the signal power in the sounder vicinity. This result is in
agreement with more rigorous theory of the anomalous attenuation effect based
on the solving of the radiative transfer equation.
