Asymptotic methods for determining the field distribution on an antenna aperture from measurements of its near field on a curvilinear surface
Abstract
The paper examines a method for the determination of the amplitude-phase distribution on an antenna aperture from measurements of the tangential component of the near field of the antenna on a curvilinear surface. An asymptotic method is used to transform the near fields measured on the curvilinear surface to distributions on a plane; the method is reduced to the Fourier transformation in rectangular coordinates and the amplitude-phase correction of the spectrum. This approach can be used in the design of multiple-element phased arrays.
