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.
由此可見，採用地麪雷達導航、由地麪火控中心發射指令的一維彈道脩正方式完全可行，竝可以做到低成本，小型化。

That makes Raytheon, which produces missiles, defence electronics, radar and ground surveillance systems, especially attractive.
