It measures the time it takes for a radio signal of a particular frequency to travel to a target and back. It also measures the strength of the signal when it returns. Based on the travel time of the signal, the radar can measure the distance of the target. Once the radar receives the 2nd signal, it can calculate the velocity of the target. The strength of the signal can be used to determine the size of the target.

What are the functions of a radar?
To detect, track, and sometimes identify objects via the emission of radio waves. Speed radar (like those used by police) can detect nearby objects and calculate their speed. Weather radar can detect the location of clouds and rain. Air traffic radar can detect and track unidentified flying objects. With the help a monopulse secondary surveillance radar, the radar system can identify the individual planes. Higher technology radars can detect and identify distant small objects with great precision.

As far as I know, radar was invented by a Hungarian scientist named Zoltan Bay. That radar was first used in World War II by the British troops.
Can radar detect stealth helicopter?
No world is a stage, and you cannot detect a helicopter unless you have the radar station (radar alone is not sufficient)
What is the difference between a Doppler radar and a regular radar?
Normal radar sends out radio waves to determine the location of an object. Doppler radar can not only find the location of an object or storm, but using something known as the Doppler effect can determine how fast it is moving towards or away from the radar.
What measures momentum?

Measures the intensity of rainfall or snowfall?

A police radar gun measures the speed of a car by?
It measures the time it takes for the radar pulse to go from the radar gun to your vehicle and back. The pulse is fairly constant so the radar gun is getting updates and by comparing the updates to the time it can determine speed.

What is a type of radar that continuously measures the wind moisture and temperature of the upper atmosphere?
doppler
What does radar do?
Radar sends out a radio wave and measures the reflected radio wave using it to calculate a target's speed, shape, material the object is made of, and direction of movement.
