Bài 2: Radar is an electronic device that can “see” great distances despite fog, rain, snow, cloud, and darkness. It can find and accurately locate missiles, aircraft, ships, cities, rainstorms, and mountains. Radar uses radio waves, instead of light waves, which the human eye uses in seeing. This makes it possible for radar to locate many kinds of objects at far greater distances than the eye can see. Radar became an important military device during World War II. Today, networks of radar lookout stations guard the United States and Canada 24 hours a day against long-range missiles and airplanes. Patrol planes and ships search the oceans with radar for hostile ships and aircraft. Airports use radar to guide planes safety to earth in fog or storms. Ships use it to steer clear of other vessels or icebergs. Radar helps weathermen warn of approaching hurricanes or tornadoes.
