摘　　要：为了实现相控阵系统的校准,降低幅相误差对相控阵系统性能的影响,提出了一种二次雷达相控阵系统的自动校准方法。分别介绍了发射校准和接收校准的流程,阐述了基于互耦原理的相控阵系统校准方法,针对二次雷达相控阵系统天线振子的结构,结合互耦校准法可以实时对相控阵系统进行校准和维护。最后通过实验证明所设计的校准方法可以有效降低了相控阵系统的维护成本和难度。In order to calibration the phased array system and reduce the impact of amplitude-phase errors,a self-calibration scheme of secondary surveillanceradar phased array is proposed.This paper introduce the process of receiving/transmitting channel calibration,describe the calibration method of phased array system based on mutual coupling principle.Base on structure of secondary surveillance radar phased array antenna element mutual coupling calibration method is used.Experment prove that the performance of the phased array can be calibrated and maintained in a timely manner,which greatly reduce the maintenance cost and difficulty of the phased array system.
