Background. The article presents a study about the functioning of electronic systems at work in the process of interference. The subject of this study is to geospatial radio model. Objective is to assess the interference performance in electronic systems, taking into account the influence of terrain.
Materials and methods. It is proposed to model the functioning of radio interference, built on the basis of geoinformation systems and methods of geometrical optics.
Results. As a result of this approach, a model for calculation and analysis of the efficiency of electronic systems, taking into account the reflection from the surface they spread.
Conclusions. Based on the proposed models can be made optimal use of frequency resources in order to reduce the level of interference to radio-electronic means, as well as to optimize the placement of transceiver stations, taking into account the surrounding terrain.
