摘要 采用全光移相网络的光控相控阵天线具有使空间波束实现宽带宽角扫描的优势。传统相控阵天线受电移相网络的自身特性限制,瞬时应用带宽有限。系统分析了典型全光移相网络的技术特点,以及各个技术合适的应用方向和方案。 Optical phased array antenna based on optical phase-shifting networks continues to be an important challenge today,despite the advances made in beam squint-free scan for ultra-wideband signals.The traditional optical phased array antenna,described as characteristics limit of electronic phase-shifting networks,is beginning to provide low instantaneous bandwidth.In this paper,we systematically analyze the technical characteristics of typical optical phase-shifting networks and discuss some of the appropriate application domain of various networks.
