系统的设计考虑近20年来,全天候防空导弹和空空导弹系统基本上都是采用半主动雷达制导。“霍克”、“麻雀”和“爱国者”是这一代导弹的代表型号。“霍克”导弹就是用照射器照射被捕捉到的目标,而“麻雀”7F和“爱国者”则是用时间分割式多功能火控雷达照射被捕捉到的目标。在历史上,只有当完成一项很特殊的任务时才选用主动雷达导引头。人们不得不在每枚导弹上耗去高额费用,以使系统符合可靠性的要求,以此来换取执行其特殊使命的价值。拿“不死鸟”
System Design Considerations For almost 20 years, all-weather SAMs and SAM systems have basically adopted semi-active radar guidance. Hawke, Sparrow and Patriot are the representatives of this generation of missiles. “Hawk” missiles were the targets that were captured with illuminators, while “Sparrows” 7F and “Patriots” were targets that were captured using time-division multi-function fire-control radar. Historically, active radar seekers have been selected only when a very specific task has been completed. People have to spend a high amount of money on each missile to make the system meet the reliability requirements, in exchange for the value of the implementation of its special mission. Take “Phoenix”
