Near-field Calibration of Active Phased Array Antenna
摘要
Abstract
In order to calibrate the phased array antenna and reduce the impact of element failure and am-plitude-phase errors,this paper proposes a calibration method which considers the mutual coupling. On the basis of the calibration with the near-field scanning method,the elements is calibrated by the rotating ele-ment electric-field vector( REV) method. With the REV method,the large-scale phased array antenna is distributed into some small areas such as middle areas and edge areas to make the signal vary more signifi-cantly . The re-calibration method can find out the failure elements and improve the phased array antenna's amplitude-phase consistency. The calibration of sub-region with the REV method can diminish the effect of the mutual coupling and shorten the calibration period. The simulations validate that the method has a good accuracy to calibrate the large-scale phased array antenna and can improve the calibration results.关键词
