What are the limitations of radar?
Limitations of RADAR are:
- It is the ability of the RADAR set to clearly distinguish two small targets on the same bearing at slightly different ranges.
- It is the ability of the radar set to clearly extinguish two targets of the same range and slightly different bearings.Factor affecting bearing discrimination : HBW.
What are the factors that affects the maximum range of radar?
What factors affect Maximum Range of RADAR?
- FREQUENCY. The higher the frequency of a radar (radio) wave, the greater is the attenuation (loss in power), regardless of weather.
- PEAK POWER. The peak power of a radar is its useful power.
- PULSE LENGTH.
- PULSE REPETITION RATE.
How accurate is a radar?
Accuracy and Acceleration Limits Under ideal conditions most police radars are accurate to about ±1 mph. Microwave moving mode radar also measures patrol vehicle speed to an accuracy of about ±1 mph. Moving mode target vehicle accuracy is ±2 mph.
Can a cop radar you going the opposite direction?
Yes, moving radar can clock other vehicles speeds while the officer’s vehicle is moving both going in the same direction or even in opposing directions. These radar guns have a second antenna that measures the patrol cars speed while the other antenna tracks the target vehicle.
How can a cop prove I was speeding?
Most police officers are trained in how to visually estimate the speed of cars. Rather, they are trained to first visually estimate the speed of the vehicle and then confirm their estimation with the radar unit. This is done because radar gun readings are often inaccurate for two reasons.
Can a cop pull you over for speeding behind them?
Sure. They slow down, you drive past them, they pull in behind you and stop you. If the reason is speeding, most mounted radar systems have the ability to determine the speed of vehicles coming up behind police cars.
Can you get pulled over for going 1 mph over?
You rarely will, but you absolutely can. There was a small town near where I grew up, that the cops were notorious for this. If you entered their jurisdiction, you knew to slow down to the speed limit or a little less. I had a friend get pulled over for 1 over and they wrote him the ticket for it.
Can you ask a police officer to see the radar gun?
Police officers are NOT required to show you the radar gun. In the state of California, it’s rather a privilege than a legal requirement for a police officer to show you the radar gun utilized to decipher the driving speed of your vehicle. However, it is up to the officer if they allow you to view the radar gun.
Can cops tell if you have a radar jammer?
Not only that, the FCC bans businesses from advertising the jammers in the first place. For most radar jammers police can tell you’re using one even if they can’t clock your speed.
Can a cops radar be wrong?
Radar guns are not infallible, and they can provide incorrect information if not operated or maintained correctly.
How long can a cop follow you before it’s harassment?
They can follow you for as long as it takes them to reasonably determine that you might pose a danger to public safety. So, for example, they might follow someone who was driving recklessly or carelessly for a period of time in order to see the driver commits any other traffic violations.
Can a police officer confiscate your car?
This law is called posse comitatus, an old concept applied when police officers didn’t have the proper resources to enforce the law. So, just as in the movies, when a cop is chasing down a suspect on foot, they technically have the right to request your car.
What to do if a police officer stops you?
Both drivers and passengers have the right to remain silent. If you are a passenger, you can ask if you are free to leave. If the officer says yes, sit silently or calmly leave. Even if the officer says no, you have the right to remain silent.
What are my rights when police stop me?
If an officer stops you while you are operating a vehicle, including a bicycle, they have the right to detain you and to ask for your identification. If you’re on foot, officers only have the right to detain you if they witness you committing a crime or reasonably suspect that you were involved in a crime.
Can you refuse to answer police questions?
No. You have the constitutional right to remain silent. In general, you do not have to talk to law enforcement officers (or anyone else), even if you do not feel free to walk away from the officer, you are arrested, or you are in jail. You cannot be punished for refusing to answer a question.
