Northrop Grumman Corporation has been awarded the first phase of a $30 million firm-fixed price U.S. Air Force contract to develop a global space surveillance ground radar system.
诺斯罗普·格鲁曼公司已经获得了美国空军第一阶段价值3000万美元的合同,以研发全球空间监视地面雷达系统。
This proves that the one-dimensional trajectory amendments mode of ground radar surveillance and progroud fire-control center control is entirely feasible and can achieve low-cost and miniaturization.
由此可见,采用地面雷达导航、由地面火控中心发射指令的一维弹道修正方式完全可行,并可以做到低成本,小型化。
