What is the Full Form of RADAR
Full Form of RADAR
The full form of RADAR is “Radio Detection And Ranging”. Radar is a detection system that uses radio waves to determine the distance, angle, and radial velocity of objects relative to the sight. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. It may also be used to explore or identify an operational object’s velocity as well as regulation. It had been secretively planned and produced by several countries during the Second World War. In 1940 U.S. navy described the word RADAR
. Also know about the details of the r full form of radar.
Working principle of RADAR
In this article, we have covered the full form of RADAR and now we are going to discuss the working principle of RADAR. Below we have listed the principle:
- RADAR works by sending an electrical signal, which is transmitted via the environment.
- On pulse track, objects recognized as targets will disperse nearly all the energy, but few are diverted back to the RADAR.
- If the targets then scattered signals combine into the receiver to develop a strong signal as distributed radiation would go into it.
Applications of RADAR
After the full form and working principle, we are going to know about the application of RADAR.
- Radars have a wide range of usage in military operations. They are used for Naval, Ground as well as Air defence purposes.
- RADARs are used to track and detect satellites and spacecraft.
- RADARs are used for safely controlling the traffic in the air. It is used to guide aircraft for proper landing and take-off during bad weather conditions.
- Law enforcement, especially highway police, has extensive use of RADARs during a pursuit to measure the speed of a vehicle.
Benefits of RADAR
There are many advantages of using RADAR. In this article, we have discussed the full form of RADAR, and the working principle of RADAR. We are going to cover the major advantage to prefer the RADAR. Below we have listed some benefits of RADAR. Also know about the full form of RADAR.
- Radar can pierce mediums like fog, clouds, snow, and mist.
- The disparity between stationary and moving targets can be determined by Radar.
- Radar signals do not require a carrying medium.
- Signals from radars can pass through isolators.
- The Radar will assess the target speed.
- Radar can aid in measuring an object’s distance.
- Radar can accurately locate an object.
Limitations of RADAR
Everything existing on the earth has two things i.e. benefits and limitations. So after the full form of RADAR and its advantage of RADAR, we will see some of its limitations of RADAR.
- Radar requires a substantial amount of time to set a lock on an entity.
- Numerous objects and mediums may interact in the air with Radar.
- Radar cannot discern multiple targets, or come up with a solution.
- Radar also has a wider beam size of over 50 ft diameter.
- The Radar has a restricted 200 ft range.
Radar can communicate from one target to another (for example, a bird from an aircraft), and some systems can recognize specific classes of targets (for example, a commercial airliner as opposed to a military jet fighter). Target recognition is accomplished by measuring the target’s size and velocity, as well as observing the target in one or more dimensions using high resolution. Propellers and jet engines alter the radar echo from aircraft, which can help with target recognition. The flapping of a bird’s wings in flight produces a distinctive modulation that can be used to detect the presence of a bird or to distinguish one type of bird from another.
Working of RADAR
RADAR transmits an electromagnetic pulse, transmitted through the atmosphere. Objects which are known as targets in the path of the pulse will scatter most of the energy but some will be reflected in the RADAR. Scattered radiation will transmit to the receiver. If there are more targets then scattered signals combine to form a stronger signal. The value of the range, position, direction, and altitude is measured by these scattered signals. The full form of RADAR is explained in this article.
