Mathematical simulation of near radiation fields for reflector-type antenna with sharp nose radom (two-dimensional problem)

Analysis of the two-dimensional simulation results of the near radiation and scattering fields of aircraft reflector-type antenna with sharp nose ogive radome are presented. The method is based on solving of the volume integral equations relatively a full field in a radome layer and integral or integro-differential equations relatively a current density on reflectors. After determination of the current density on screens, which simulated reflectors, and the field in a radome layer, the estimation of the field nearby antenna system (under and outside radome) reduce to the quadrature calculations, used integral representations of the fields.
