Vayyar Imaging Announces 4D Point Cloud Application for Automotive Sensors
This new single-chip radar monitors conditions both inside and outside of the vehicle.

Vayyar Imaging’s 4D point cloud application for automotive sensors gives cars a view of everything happening both inside and around a vehicle. Vayyar’s radar on a chip creates
a moment-by-moment visual map. The map covers passengers inside the vehicle, as well as pedestrians and objects from without.
4D point cloud data is based on 3D images with a 4th dimension – time. It is a time series of 3D images. Through it, a 3D image can be represented and analyzed over time. Thus, more than just locations, shape and dimensions, but also movement information is captured. The car’s total environment can be completely classified.
Radar on a Chip
Vayyar’s radar-on-a-chip (RoC) includes 48 transceivers at 76-81GHz and this allows over 2,000 virtual channels. The RoC also encompasses an internal DSP to allow for real-time signal processing.
Vayyar’s exterior solutions can enable mapping and classification of the car’s external surroundings. This will make possible:
- Parking assistance through trajectory mapping and object detection
- Blind spot detection
- Lane switching assistance for drivers
- Alerts for height obstacles and obstructions
With Vayyar’s sensors, systems can be devised that go beyond warning of potential driving mishaps.
In-cabin solutions can include:
- Tracking the driver’s vital signs
- Measuring the driver’s head movement and position
