Naval ships have little time to defend against modern missiles that home in on targets at 32.18 km a minute at surface-low height. But scientists at the Naval Research Laboratory, Washington, are working on a new radar system that promises to detect such threats faster. It could also improve the radars used for air-traffic control, weather warnings and pollution monitoring. The key component of the new radar is a mirror which can reflect 5,000 radar beams every second, each one in a different direction. This would enable radar operators to monitor a 360-area while tracking multiple missiles ( Business Week , June 3, 1996).
