Do you mean Doppler radar?
If so, Doppler radar measures velocity. It's a specialized radar that makes use of the Doppler effect to produce velocity data about objects at a distance. It does this by beaming a microwave signal towards a desired target and listening for its reflection, then analyzing how the frequency of the returned signal has been altered by the object's motion. This variation gives direct and highly accurate measurements of the radial component of a target's velocity relative to the radar. Doppler radars are used in aviation, sounding satellites, meteorology, police speed guns, and radiology.
The specific term "Doppler Radar", due in part to its extremely common use by television meteorologists in on-air weather reporting, has erroneously become popularly synonymous with the type of radar used in meteorology. Most modern weather radars use the pulse-Doppler technique to examine the motion of precipitation, but it is only a part of the processing of their data. So, while these radars use a highly specialized form of Doppler radar, the term is much broader in its meaning and its applications.

Why can't radar be used to measure the distance to stars?
Radar can only be used for planets close to us in the solar system and the planet or object must be able to reflect the wave back. Radar cannot be used to measure the distance between Earth and the Sun because the sun doesn't reflect the radio waves back.
Are radars and chronometers alike?
No. RADAR stands for RAdio Direction And Ranging. RADAR uses the reflection of pulses of radio waves from objects to measure the direction and range (distance) of the objects from the RADAR unit. Some RADAR units also measure relative speed by measuring the Doppler frequency shift. Chronometers are simply very precise clocks.
What is square units measure?
Square units measure area.
Is there a radar detector that also has GPS?
Several companies like Beltronics and Uniden make gps units that feature radar detecting features but it is probably for the best to by separate stand alone units.

How high can a radar operate?
Radar is just another pulsed electromagnetic wave, and may travel freely throughout space. Radar transponders are left on our Moon and measure orbital variations. The upper frequency limit is only defined by our ability to operate technology at high frequencies. Light radar (lidar) is commonly used on the highway, albeit in Doppler mode. There appears to be no practical limit to operational height. -- The Doppler Weather Radar units operated by NOAA/NWS are routinely mounted on towers at least 100-ft off the ground. -- Air Route Surveillance Radar (ARSR) installations are routinely constructed on mountaintops. -- All commercial airliners and military aircraft are equipped with Radar units, which function quite satisfactorily while in flight. -- Side Aperture Radar (SAR) has been used aboard the Space Shuttles and other artificial Earth satellites to map the Earth's surface, with spectacular success. -- Radar units have been used very successfully to map the surfaces of the moon and several planets.
What does radar for?
Radar is a system that uses radiowaves to measure things like size, distance and speed of a specific object.
When was RADAR first used for baseball?
Radar was first used to measure the speed of a moving object in 1935. By 1938, they were used to measure the speed of a fastball thrown by Bob Feller.
