Yes. The radar calculating unit is reading more than one speed. It reads the patrol car speed from stationary objects (the ground, signs, etc.) and subtracts that speed from the speed at which your car and his car are coming together.
If the patrol car is doing 38 and you are doing 55, the radar unit will read 38 from the ground and 93 from your car. It subtracts the 38 from the 93 and displays your speed as 55.

How accurate is a police radar gun when the car is going down hill?
Very accurate, it measures speed and doesn't care if the vehicle is traveling up or down, toward or away from the radar gun.
Is police radar accurate through their rear window?
Yes. The glass does not affect the radar.
Are police radar guns accurate at one half mile?
Yes, barring interfering factors.Another View: I'm not certain that the customary hand-held models of police radar can be accurate at that range, and concede that they could be, depending on the equipment, but I DO know that speed checkiing lasers ARE accurate at that distance.
Can a Police Officer use Radar to clock the speed of a car while the Police Officer is driving?
The answer is "yes." Traffic radar monitors both the speed of the vehicle in which is it mounted and the speed of "target" vehicles coming toward or moving away from it. On the radar display, the officer sees two speeds: "patrol" (the speed of his vehicle) and "target" (the speed of the vehicle the radar is tracking). the target speed measurement is equally accurate, whether the patrol vehicle is moving or not.
Can a police offficer traveling in the south bound lane on a highway take radar on a vehicle traveling in the north boun d lane?
Yes, there is radar equipment capable of it and it is most definitely within the capability of laser speed measuring devices.
What is a police radar?
A radar that the police use to detect stuff.
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.
Can radar detect accurate speed going opposite direction?
Yes, radar can accurately detect the speed of objects traveling in the opposite direction. Radar measures the speed of objects based on the Doppler shift principle, which is independent of the direction of movement. By analyzing the frequency shift of the radar signal, both the speed and direction of the moving object can be determined.
Do they make a detector that locates police?
There is a device called a radar detector, but it will only detect a radar signal, not police in general.
How does a police radar work?
i don't the answer
Do the police have to show you the radar in Illinois?
It is not a requirement to show RADAR readings in Illinois.
What are the benefits of having a radar detector?
Having a radar detector will alert you when a Police Car with its speed radar is near. The Radar Detectors will produce an audible signal alerting you of this, and will do so far in advance of when you are able to see the Police Car.
