摘要
Abstract
A new method for reconstructing array antenna aperture by use of nearfield measurement sys-tem is presented.In the method,the acquired near-field data is transformed into plane wave spectrum (PWS),in which the antenna element factor is compensated.Then the amplitude and phase distributions of every antenna element feed port on aperture surface of array antenna are compensated.The element channel error is added to the ideal near-field data through computer simulation.The result of inconformity of ele-ments is also analyzed.This method has high inversion precision and improves the efficiency of array antenna aperture correction effectively.关键词
