国外天基预警雷达系统发展现状及关键技术

天基预警雷达作为重要的信息获取手段,其采用多种工作模式,可探测空间、空中和地面目标.鉴于天基预警雷达系统的战略地位,美国、俄罗斯和加拿大等国竞相开发该系统.总结了天基预警雷达系统的国外发展现状及关键技术,简要介绍了天基预警雷达的未来发展趋势,指出美国虽怀疑其“天基雷达计划”的可行性,但仍非常重视天基雷达各项关键技术的研究.

Current developments and key technologies of foreign space-based warning radars

As an important information acquisition method,space-based warning radars with multiple work modes can detect various space,air and ground targets.In view of the important strategic position of space-based warning radars,many western countries such as USA,Russia and Canada are now racing to develop the radars.This paper summarizes current developments and key technologies of space-based radars,discusses their developing trends,and finally points out that USA still pays attention to the key technologies study of space-based radar although the feasibility of its Space-based Radar Plan is doulted.
