Restoration of characteristics of mirror antennas on the basis of modelling process of measurements of a field in a near zone

The decision of a problem of restoration of characteristics of mirror antennas on the basis of modelling process of measurements of a field in a near zone is considered. As the exact decision the diagram of an orientation calculated by an aperture method on the set distribution of a vector of intensity of an electric field in the aperture of the aerial is accepted. Restoration the diagram of an orientation on the sources set in a near zone is carried out, and as sources of an electromagnetic field the equivalent electric and magnetic currents calculated by an aperture method on a rectangular of measurements are used. Estimations of restoration the diagram of an orientation within the limits of the main thing and two lateral petals are resulted.
