EXAMPLE:
- INPUTS:
- Radar emitted transmitter frequency = 24.125 GHz
- Difference in frequency between transmitter and received echo = 5 Hz
- OUTPUTS:
- Vehicle Speed in Kph (Km/hour) = 31.088
- Vehicle Speed in mph (miles/hour) = 19.317
Formula for Radar Vehicle Speed Calculator
Here’s the formula or equation used by Radar to calculate the speed of a moving vehicle:
Alt text: Radar vehicle speed calculator formula
The vehicle speed calculation formula shown above is used by both radar guns and radar speed signs.
Alt text: kph to mph conversion
Unit conversion from Kph (kilometers per hour) to mph (miles per hour) is done by multiplying the Kph value by a factor of 0.621371.
