Radio Detection And Ranging
Radio Detection And Ranging, commonly known as RADAR, is a detection system that uses radio waves to determine the range, angle, or velocity of objects. In the context of aerospace engineering, RADAR is used to detect aircraft, spacecraft, weather formations, and terrain. The radar dish or antenna transmits pulses of radio waves or microwaves which bounce off any object in their path. The object returns a tiny part of the wave's energy to a dish or antenna which is usually located at the same site as the transmitter. RADAR systems are widely used in navigation, meteorology, and even in the technology of guided missiles. In aviation, aircraft are equipped with radar devices that warn of obstacles in or approaching their path and give accurate altitude readings. In space technology, RADAR is used for satellite tracking, space surveillance, and for planetary observation and exploration.
