Aptiv MRR
The Aptiv MRR (medium-range RADAR) is used to detect targets (pedestrians, bicycles, motorcycles, cars, trucks) ahead of a host vehicle. The Aptiv MRR system is intended for a variety of automotive applications including adaptive cruise control, driver alert and collision mitigation functions. The MRR has a range of 160m and a horizontal field of view of >90 degrees.
