The radio waves hit anything they come into contact with and are bounced back to the radar set. These radio waves show, on the radar screen, the outline of the object they bounced off. A radar screen is much like a television screen, except that it does not show as clear a picture. The picture on a radar screen is usually the outline of an object like an airplane in the sky.

The guns start to fire when the enemy aircraft get within range. Modern anti-aircraft guns are fired automatically and do not even have to be aimed by the soldiers. The radar set does everything.
