Can radar work when police in motion?
No. With police officers in motion, it would appear that cars would be going slower. Say that a car is going 50 MPH, and you are going 45 MPH. Eventually the vehicle wil be ahead of you. Now say you are a police officer with radar. If you test this car, it will appear (on radar) that the 50 MPH car is only going 5 MPH, thus to get the accurate speed, you must be going 0 MPH.Disagree. The original police radar required a stationary unit. Radar is use for the past 30 years is capabable of adding or deducting the speed of the police car from the observed speed. It does not require that the police car be in one fixed spot.Added: The second cotributor is correct. I seriously doubt that any of the old radar units are still in operation much less certifiable as accurate. ALSO: the term "radar" is a commonly used by the the public to describe ALL police speed-clocking devices. Any of these can be calibrated to be used while the vehicles are in motion.
