Radar incorporates radio waves to establish the range,altitude,direction,and speed of objects both in the air and on the ground. Radar is also used in meteorology to determine weather formations and can also be used to map terrain. Typically,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 | |
