据美《微波系统新闻》1978年3月报道:经过几年有节制的研究活动之后,美国国防部又打算研制各种类型的新雷达系统,其中包括靶场试验用雷达、防空预警雷达、大气层外和大气层内情报收集雷达、空间雷达以及舰载雷达(卽舰载监视雷达系统)等。最近,海军电子系统司令部与雷声公司签定合同,要求研制“宽区域有源监视系统”(WAAS)。WAAS是海军第一部用作靶场测量雷达的陆基相控阵雷达,将架设在波多黎各的一座山顶上,俯视“罗斯福路试验靶场”。它是一部多功能雷达,可在海面
According to the U.S. Microwave Systems News, reported in March 1978: After years of moderation in research activities, the U.S. Department of Defense also plans to develop various types of new radar systems, including range test radar, air defense early warning radar, and extra-atmospheric And atmosphere information collection radar, space radar and shipborne radar (卽 shipborne surveillance radar system) and so on. Recently, Navy Electronics Systems Command signed a contract with Raytheon for the development of a WAAS (Wide Area Active Surveillance System). The WAAS is the first Navy ground-based phased array radar to be used as a rangefinder radar and will be mounted on a hilltop in Puerto Rico overlooking the Roosevelt Road Test Range. It is a versatile radar, available on the sea
