摘要
Abstract
For calibrating the phase center (PC) of array antennas precisely, a calibration method on the PC of array antennas is proposed. Firstly, the relationship between the phase radiation pattern and the position offset of the array antennas is derived. Secondly, based on the definition of the phase center of the array antennas and the steps of calibration, the precise value of the phase center is calculated by the least square method (LSM). Then, the proposed calibration method is verified by simulation. The error analysis of the simulated results indicates that a wider half power beam width (HPBW) and a higher measurement accuracy can enhance the calibration accuracy of the phase center of array antennas.关键词
