RADAR stands for Radio Detection And Ranging. It can also be used to detect the speed and direction of an object.
RADAR works by sending electronic signals which are transmitted through the atmosphere. Targets that are in the pulse path will disperse most of the energy but some of it will also be backscattering to the RADAR. Dispersed radiation will go back to the receiver. If there are more objects in the RADAR then the scattered signals will form a larger and stronger signal as all the distributed radiation will go into it. The values of range, position, direction, and altitude are determined by these dispersed signals.
The first RADAR system was developed in 1935 by British Physicist Sir Robert Watson Watt and by 1939 England had created their RADAR systems along its south and east coast to detect aggressions from air or water.
The signals used by RADAR technology are not obstructed or limited by snow, clouds, fog, or mist. Even in very difficult conditions, data will be collected.
Materials that are considered to be insulators such as rubber and plastic do not obstruct or impede RADAR signals to collect data. It will go through these metals and acquire the necessary data.
The data acquired by the RADAR system can be used to map an area and provide 3D images of the data through various angles the data is captured.
RADARS are cheaper as compared to other instruments and are very affordable for large-scale projects.
RADAR Systems are quite fast if the area to be covered is not too large.
The RADAR systems can be used by industries all across the world for various other usages.

Radio signals travel freely in the air and space it takes slightly more time to reach a target and get back.
They operate at a limited range of not more than 200ft.
If there are multiple objects it becomes tough for a radar system to tell the objects apart.
The signals from a RADAR system are often very oversensitive which may lead to inaccurate data.
The RADAR can not decipher the color of the target.
The radio signals released from a RADAR do no work beyond the ionosphere. If they go beyond the ionosphere they are reflected back to the earth.
