Simulation of MM-radiowave scattering over statistically uneven surfaces

The work presents the results of numerically simulating the problem of EM MM-wave scattering over statistically uneven surfaces of natural and anthropogenic origin with regard to directional pattern. Calculations have been made using the perturbation technique and the tangential planes technique. The influence of wavelength, elevation of radiation source above the Earth´s surface, angle of sight, electrophysical and statistical surface properties on scattered fields has been studied. The available mathematical and software tools allow for the scattered field and the absolute cross-section to be calculated for varied geometrical and electrophysical parameters of the problem. These investigations have been carried out with the aim of simulating a MM-wave radar radio channel. We intend to develop the model to encompass compound pulse probing signals and actual directional patterns.
