MIMO, Beamforming Methods Enhance Auto Radar Angular Resolution (.PDF Download)

Who would have thought that something as complex as radar would turn out to be one of the best sensing methods for implementing vehicle safety features like advanced driver-assistance systems (ADAS)? Such systems now rely on multiple sensors to detect surrounding objects. These include video cameras, ultrasonics, radar, and LiDAR. However, recent developments indicate that radar may be most versatile sensors for automotive applications.

Sensor Sensibility

A variety of sensors are used for proximity detection; that is, sensing the direction and distance and even speed between objects. Such sensing is at the heart of ADAS and autonomous driving systems. Currently used sensors come with benefits and limitations.
