摘　　要：有源相控阵系统波束扫描主要通过TR组件通道中的延时器或移相器来实现,当通道扫描状态不同步时,可能导致发射状态下天线阵有源驻波恶化,对相控阵系统造成危害。针对此种情况,进行仿真评估以及危害分析,提出解决和避免手段,并最终在项目中得到验证。The beam scanning of active phased array system is mainly realized by the delayer or phase shifter in TR modules.When the beam scanning is out of synchronization,the active VSWR of the array may be distorted in transmitting mode,which does harm to the phased array system.The simulation evaluation and hazard analysis of this situation is carried out,and the methods for avoiding this problem are presented,which are verified in the project finally.
