Abstract

A method for near-field reconstruction in indirect far-field systems is provided. The method comprises the steps of measuring a reference antenna for orthogonal field components in a direct spherical near-field system at a well geometrically defined distance (R0), measuring the reference antenna for orthogonal field components in an indirect far-field system and optimizing the orthogonal field components in the indirect far-field system with respect to the orthogonal field components in the direct spherical near-field system.
