Research on the high precise calibration of the GPS receiving antenna phase center

摘要

The paper introduces a new method of calibrating GPS receiving antenna phase center in Anechoic Chamber. Based on the practical measured phase pattern, calculating the phase center and correcting the phase pattern repeatedly using the method can improve the calibration accuracy. And the method is free of the multipath and environment. The simulation results validate the calibration method is feasible and can obtain a higher calibrating accuracy.
