Radar or LIDAR (laser measurement of speed) has to be directed toward or away from the path of a moving vehicle, as it measures the speed vector between the measuring device and the vehicle. Traffic radar or LIDAR will not measure the speed of a vehicle moving at a right angle to the direction it is pointed.
What else can I help you with?
Do cops have rear radar?
Yes, some police vehicles are equipped with rear-facing radar units that can detect the speed of vehicles behind them. This allows police officers to monitor and enforce speed limits for vehicles approaching from the rear.
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.
What is that thing police use to clock how fast a car is going?
Radar Gun
What is a police radar?
A radar that the police use to detect stuff.
Are radar detectors legal in North Carolina.?
Radar detectors are legal for passenger vehicles in North Carolina. However, they are prohibited for use in commercial vehicles. It is important to note that while radar detectors are legal, the use of radar jammers is illegal in North Carolina and throughout the United States. Radar detectors are devices that can detect radar signals emitted by police radar guns, while radar jammers are devices designed to interfere with or block radar signals.
Do police have radar to find drugs in cars?
No. No. RADAR doesn't work that way. Right now, dogs are the hi-tech solution of choice for detecting the presence of contraband drugs in vehicles.
What is an advantage of a radar gun?
Generally speaking, it allows police officers to check the speed of other vehicles in order to enforce traffic laws.
Can a police radar gun detect your license plate number?
No, police radar guns are designed to measure the speed of vehicles, not capture license plate numbers. License plate numbers are typically recorded by cameras used in automated license plate recognition systems.
Which effect is used by police to check over speeding of vehicles?
It varies state to state, but usually it's the ol' radar gun. In some places they use police helicopters and radar to check a vehicle's speed. Other states also use plain, unmarked cars to "pace" another car.
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.
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 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.
