摘　　要：本文介绍了一种应用于卫星通信的车载光控相控阵天线的关键技术设计,并对天线元、天线阵和光真延时等关键部件进行了仿真,表明采用光真延时技术的相控阵天线具有宽频宽角扫描的特点,可以较好地解决传统相控阵天线无法应用于宽带通信系统的问题。A system of optically controlled phased array antenna on vehicle for satellite communication is presented.Key technique of the system is analyzed and performance of antenna element,array and optical true time delay units is tested through computer simulation.Simulation shows that optically controlled phased array antenna has a feature of wideband and wide-angle scanning.Optically controlled phased array antenna with this feature overcome a difficulty that conventional phased array cannot be applied for wideband system.
