摘要：
Near-field measurements can be used as diagnostic cools Co reconstruct aperture field distribution of planar array antennas and to locate their possible defective elements. In this paper, a method for obtaining the individual element excitation of an array antenna from measured near-fields is presented. A computer simulation is performed to evaluate tile effect of various near-field parameters such as the measurement distance and the sample spacing on the reconstruction of the excitation, The validity of the approach has been verified using both synthetic and actual measurements data. Good results have been obtained.
