The Radar Detector Source

Posts Tagged ‘cars’

There has been a a lot of police activity by my house, but that is not what this is about.
My question is (bare with me hard to explain). I have two police radars/detectors in both of my cars one in a SUV and another just in a plain car, they are both extremely powerful and have beep and voice control when ever a 5-0 is near by.
So the question is… You know how they work with a cigarette lighter in the car, the main source for the radar. Well, I have two Car/charger converts which converts them to a home AC outlet source. So they can be used at home.Kind of like converting a USB Into a charger with the AC plug. Get my point. What is i do that and set up to radars in my room pointing different angles.
The key here is where im a place them is right next to big windows in my room so i will get good Satellite signals, When ever a 5-0 passes by I will be alert, What do you think? If you are to scared to answer this question please dont just leave…and the rest of you guys, you know who i am talking to?
*JUST DONT LET ME FIND OUT THIS IS ILLEGAL*
The radar/detector system is there to alert me if a cop is by my house or not, can it pickup on that

A police cruiser sets up a novel radar speed trap, consisting of two transmitting antennas at the edge of a main north-south road. One antenna is 2.0 m [W] of the other. The antennas, essentially point sources of continuous radio waves, are fed from a common transmitter with a frequency of 3.0 x 10^9 Hz. The trap is set for cars travelling south. A motorist drives a car equipped with a radar detector along a east-west road that cross the main road at a level instersection 1.0 x 10^2 m [N] of the radar trap. The motorist hears a series of beeps upon driving west through the intersection. The time interval between successive quiet spots is 0.20s as the car crosses the main road. How fast is the car moving?

A police cruiser has an unusual radar speed trap set up. It has two transmitting antennae at the edge of a main road that runs north and south. One antenna is 2.0 m[west] of the other, and they are both fed from a common transmitter with a frequency of 3.0 x10^9 Hz. These antennae can be considered as point sources of continuous radio waves. The trap is set for cars travelling south. A student drives his car along an east-west road that crosses the main road at a level intersection 100 m[north] of the radar trap. The student’s car has a "radar detector", so he hears a series of beeps as he drives west through the intersection. If the time interval between successive quiet spots is 1/5 s, as he crosses the main road, what is his speed?
