Detection range of radar sensor (schematic) 

With a low radar beam divergence 9° (sharp focussing), the radar sensor covers only a very narrow area in front of the vehicle. For this reason, it is only used above a speed of 30 km/h (at greater distances). Its detection range measures up to 200 m.

The radar sensor, which functions according to the "Pulse Doppler Principle", can measure the distance and the speed of individual objects (vehicles) independently of each other.
