| 摘 要： | 介绍了EAST低杂波天线相位采集控制系统中两个主要部分的相位本底的校准技术。一是由相控多结波导阵天线与等离子体相切弧面引入的相位本底的静态校准,二是天线移动时软波导伸缩引起的可变相位本底的动态校准。低杂波天线相位本底校准技术为相位反馈控制系统提供了准确的相位基点,为实现预设相位与实调相位的一致性奠定了基础。

| Abstract: | A calibrate technology of background phases in two main parts is introduced in the EAST lower hybrid wave antenna phases collection and control system.One part is referred to static calibration of the background phases caused by tangency of phased multi-junction grill antenna and plasma.The other part is referred to dynamic calibration of the alterable background phase caused by soft wave-guide flex when the antenna is being moved.The calibrate technology of lower hybrid wave antenna background phases provides an exact phase base point of phase feedback control system.It could be a foundation for the consistency of the pre-establish phases and actual phases. |
