6跟踪天线系统的过去、现在和未来显示文摘约半个世纪以前,由于第二次世界大战需要,发展了自动跟踪技术。美国陆军在1942年首先制成的自动跟踪产品是SCR-584雷达。早期的跟踪系统天线由天线和万向节组成,以保证跟踪目标时天线波束的正确位置,伺服机构控制万向节的运动,操作手通过控制系统控制跟踪,发射机照射目标,而接收机接收反射信号,从中提取跟踪误差信号并送给伺服系统。值得注意的是这里的论述也适用于现在的跟踪系统,实际上遥测信号跟踪是被动式的,不需要发射机,真正的某些现代跟踪天线不需要用万向节支持,但跟踪系统的基本要素仍然是相同的。然而在过去50年里,可用材料、元器件、方法和技术都有重大的变化和进步,本文讨论范围只限于天线和它的技术发展变化,叙述跟踪系统简史,讨论近年来各种跟踪天线的发展以及目前和未来的跟踪技术。Authur Sullivan 许福仁 1990国外导弹与航天运载器1990,,10:1
