测量型阵列天线相位中心标定方法研究

Array Antenna Phase Center Calibration

为解决阵列天线相位中心标定的工程实现难题，根据视在相位中心的定义和对阵列天线的工作原理分析，提出了阵列天线相位中心的拟合递归测试方法，并在传统相位中心直接标定法的基础上，提出了单个波束的相位中心比对标定法。实验证明该方法降低了测试成本，提高了工作效率。

In order to solve the project implementation problem of array antenna phase center calibration, according to the definition of the apparent phase center and the working principle of the array antenna analysis, the array antenna phase center of the fitting method of recursive testing, and phase center in the traditional direct calibration law proposed on the basis of a single phase center of the beam than on the calibration. Experiments show that this method reduces test cost and improve efficiency.
