-
The full form of RADAR is Radio Detection And Ranging. It is a system that uses radio waves to detect the range, angle, and velocity of the objects. It can be used to detect moving objects such as aircraft, ships, spacecraft, guided missiles, etc. RADAR was developed by many countries for military use during World War II. The term RADAR was given by the united states in 1940.
Major parts of RADAR system
Given below are 6 major parts of a RADAR System:
1.Transmitter-The signal is first generated using a waveform generator and then amplified in the power amplifier.
2. Waveguides-It is used for transmission of RADAR signal.
3.Antenna-The antenna used can be a parabolic reflector, planar arrays.
4.Duplexer-It allows the antenna to be used as a transmitter or a receiver.
5.Receiver-The receiver consists of a processor to process the signal and find it.
6.Threshold Decision- The receiver output is compared with a threshold to find the position of the object.How does radar work?
RADAR sends electromagnetic waves, transmitted through the air. Target objects in the way of waves will disperse the vast majority of the vitality yet some will be reflected back to the RADAR. scattered radiation will go to the recipient. On the off chance that there are more targets, at that point, scattered signals consolidate to frame a more grounded signal. The estimation of range, position, bearing, and height is estimated by these scattered signals.Applications of RADAR
1. It is used in Military to detect and recognition of target
2.Used in the missile system to guide the weapons.
3. It is used to control air traffic
4. By Precision Approach RADAR provide guidance to aircraft in bad weather
5.Used in weather forecast to determine the weather
6. It is used to determine the composition of the earth's crust.
7. It is used to find and track the position of satellites
8. guide the space vehicle for a safe landing on the moon
