RADAR

This radio instrument finds the position and distance of objects which the human eye may not be able to see: it also records the direction and speed of moving objects, such as ships and airplanes. Radar can pick out objects more than a hundred miles away in the worst weather conditions, when we can see perhaps no farther than a hun­dred yards.

Radar works in this way. Powerful transmitters send out a stream of radio-waves, called «pulses», at the rate of perhaps one thousand every second. These pulses shoo/ through the air at a speed of one hundred and eighty-six thousand miles a second till they hit an object, perhaps a ship, an airplane, an iceberg or a hill. These pulses can­not go though the object: and so they immediately shoot back at the same speed, in the opposite direction, and hit the aerial of the radar. The moment this happens, a spot or line of light appears on the radar screen, showing the position and distance of the object.

Today radar is used for many peaceful purposes all over the world. Modern ships of all nations carry radar to help them sail in had weather , when it is possible to see for a distance of perhaps only a few hundred yards.

Radar also helps to guide airplanes across the world. Radio signals sent beams are transmitted in to the sky from land radio stations at a number of points along their course. The pilots can hear these signals on their radio and see them on their radar screen. The beams are like sign-posts in the sky. A pilot guides his airplane towards one beam, and then flies on to next beam. At the end of his journey, he will land his airplane with the help of ra­dar. Trained men at the airport watch the airplane on their radar screens and tell the pilot by radio the course to follow, they tell him when and by how much to reduce height, and give any other orders that may be necessary.

In many countries radar controls the speed of cars on roads where there is a speed limit. They hope that radar will help them reduce the number of accidents on the roads. Thousands of people all over the world lose their lives in road accidents every year. The police can now watch the speed of the cars on their radar screens and stop mo­torists from driving too fast.

Radar is used to forecast the weather, and to study the moon and stars. Powerful radar telescopes are used to study the stars. They are also used to study scientific experiments in space.

Almost every year some new use is found for radar. Radar is one of the most important scientific discoveries in the field of engineering of our time.
