Simple numerical model of radio wave multiple scattering effects in the ionospheric plasma layer

Abstract

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.
