Radar Sensor (ADAS)
A radar sensor uses radio waves to measure the distance and speed of objects around the car.
What is Radar Sensor (ADAS)?
Front radar sits behind the grille or badge; corner radars in the bumpers. It works in darkness and fog better than cameras. Mounting angle is critical. Radar sensors report "sensor blocked" in heavy snow or when covered with mud. Some are heated. Most use the 77 GHz band; older ones used 24 GHz.
How it works
It sends radio waves and analyses the reflections.
Why it matters for your car
Even small knocks can misalign the radar. Aftermarket badges or plates in front can block it.
