Modeling of Complex Electrodynamic Objects Based on a Combined Approach

Abstract

The paper deals with the problem of assessing the characteristics of electromagnetic wave scattering on electrodynamic objects with a complex shape. A combined approach, which is based on the use of statistical methods, methods of fuzzy estimation, and expert analysis, is proposed. A numerical estimate was determined for the index characterizing the level of scattered electromagnetic fields. Linguistic values of the indicators based on expert evaluations were compared. Numerical evaluations of the characteristics of the electrodynamic objects surveyed were given. Based on the formed information base, the frequency of occurrence of different responses was calculated for the analyzed groups, which included objects with over reflections (which was considered as the main group, and objects without over reflections (which was considered as the control group). The values of the electromagnetic wave scattering angle limits under the analyzed scattering conditions were demonstrated.
