How Does Radar Work?

Radar is an electronic detection system which makes use of radio waves for determining the speed, direction, or distance of objects. It is often used to detect boats, airplanes, vehicles, human beings, and other objects. In the US, radar is defined as’Radar Scanning’, where it is used to locate objects on the ground, but is also often used in military operations. Radar is widely used across the world and has many applications in different fields. In fact, radar detection technology is used in everything from search-and-rescue operations to shipping, while the military, aviation, and telecommunications industries make extensive use of radar in all domains.

Radio Frequency Identification (RFID) is another term that is commonly used to describe the radar, although in this case we are talking about radar detection. Radar operates by detecting changing magnetic fields, which are emitted by moving objects, in our atmosphere. These changing magnetic fields are identified by changes in the amount of electromagnetic radiation being emitted. This radiation is in the form of pulses, which are measured by antenna sensors. When these pulses are detected by the sensors, the frequency of the radio signal being emitted is matched with the pulses.

Radar systems measure the time and location of the radar’s transmission by means of Doppler shifts in the transmitter and receivers, which are positioned close to the radar’s intended target. The transmitter is usually mounted on the aircraft, and its position and azimuth is used to determine where the receiver is pointed. This method is used to ‘know’ what direction the aircraft is travelling towards, and is useful for navigation, as well as for controlling other functions of the aircraft. Radar is particularly useful for blocking out external sources of noise, such as aircraft engines and low-flying birds.
