Police use of Doppler radar to detect violations in cars. Explain how the Doppler effect is used in this application. ?
Read about the Doppler effect, but I still do not understand how the police used to accelerate the car?
This is what I think: normal radar given car speed, but with the Doppler effect know if the frequency is becoming more or less. If it is higher, the car is approaching. If lower, the car moves away.
