Relative Velocity

WARNING: This page is about a different car, the 2015 Jaguar XF, 2014 Jaguar XF, and 2013 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.

When the signal is reflected off a vehicle moving at a different speed (opening or closing the gap) an effect known as the 'Doppler Shift' causes an extra frequency modulation to be imposed on the signal. This doppler frequency varies with the relative speed of the vehicle being followed, enabling the system to differentiate between vehicles traveling at different speeds and also between moving vehicles and stationary objects.
