Diffraction of an electromagnetic wave on a countless number of scatterers

Abstract

Topicality. The task of finding the radar cross-section (RCS) of complex objects is of great importance. Usually, when creating radar stations, RCS is measured on real targets. The possibility of accurate theoretical calculation according to the previously created algorithm accelerated the development of new radar stations.

The goal of the work. The method of work is to create an algorithm for calculating the RCS of real targets with the help of their simulation using systems of brightly unpolarized points in space.

Materials and methods. MATLAB computer support was used to solve the problems of modeling complex objects with the help of a large number of bright non-polarized points. All levels were derived from or from the radar level.

The results. Different levels are obtained for the near zone without and with diffractive scattering, as well as similar levels for the far zone and all graphs are given with an overview.

Conclusions. Thus, in this paper, the definition of effective surface scattering was formulated, and formulas for systems with 3 and 4 scatterers were given for the incoherent case without diffraction scattering for the near and far zones, for the incoherent case with diffraction scattering for the near zone, for the coherent case without diffraction scattering. for the far and near zones, for the coherent case with diffraction scattering for the near zone. Numerical calculations performed at these levels were also presented.
