Radar, illustration. Radar uses radio waves or microwaves to establish the range, altitude, direction, and speed of objects both in the air and on the ground. A dish or antenna emits radio waves, or microwaves, which bounce back from objects in their path. Radar is an acronym for Radio Detection And Ranging. | |
