Israel semiconductor vendor Vayyar has launched a single-chip radar for the automotive market that uses real-time 4D visualization of both car interior and exterior environments.

The radar displays the dimension, shape, location and movement of people and objects for classification of the car’s environment, no matter the lighting or weather conditions.

The in-cabin solutions based on the radar include seat belt reminders, optimized airbag deployment, gesture control, driver drowsiness alerts and infant detection alarms. Exterior solutions include 360° mapping, enhanced parking assistance, blind spot detection, lane switching assistance, automatic speed and distance control and alerts obstacles, pedestrians and other cars.

The radar-on-a-chip contains 48 transceivers at 76 to 81 GHz, allowing for more than 2,000 virtual channels. The chip can be integrated into existing automotive framework, cutting the number of sensors needed for vehicles.
