Vayyar Imaging has launched the world’s first multi-range ‘XRR’ 4D imaging radar chip – a single RFIC with a range of 0-300m, designed for passenger cars, trucks and motorcycles. Supported by a 48-antenna MIMO array, the leading-edge platform provides radar imaging with unprecedented accuracy for numerous safety applications, without the need for external processors.
Vayyar’s XRR chip – AEC-Q100 qualified and ASIL-B compliant – offers an ultra-wide field of view and rich 4D point cloud imaging, delivering unprecedented multifunctionality on a single-chip platform, and able to support dozens of advanced driver assistance systems (ADAS), advanced rider assistance systems (ARAS) and autonomy features. Vayyar says this eliminates the need for multiple, costly vehicle sensors and reduces costs, complexity, hardware, software, power consumption, wiring and integration efforts.
Affording a range of 0-300m, the multi-range XRR chip differentiates between static obstacles such as dividers, curbs and parked vehicles, and between different types of VRUs, moving vehicles and other hazards. In low-speed environments such as parking lots, the XRR chip’s uSRR and SRR sensing supports advanced parking assistance, scanning the vehicle’s surroundings for pedestrians and obstacles.
On the open road, MRR and LRR capabilities facilitate a variety of ADAS and autonomy applications such as Lane Change Assist (LCA), Adaptive Cruise Control (ACC), Blind Spot Detection (BSD), Collision Warnings (fCW/rCW), Cross Traffic Alerting (CTA) and Autonomous Emergency Braking (AEB).
“Vayyar’s XRR chip delivers unparalleled multi-range capability, reducing complexity and costs, so that high-end safety is accessible and affordable for all vehicle models,” said Ian Podkamien, VP and head of automotive at Vayyar. “To achieve this, we integrated 48 transceivers into a single chip, along with the computing power necessary for optimal performance, while maintaining cost-efficiency and a compact form factor.”
Just two XRR chips earn any vehicle 33 Euro NCAP safety points, while replacing over 10 traditional ADAS sensors, according to the company. Vayyar’s platform supports nine different Euro NCAP ADAS requirements for 2023, protecting pedestrians, cyclists and motorcyclists, while maximizing safety ratings.
Compared with alternatives such as cameras, standard radar and lidar, Vayyar says its 4D imaging radar delivers unprecedented multifunctionality on a single-chip platform, maximizing affordability, coverage, range, resolution and robustness. The XRR chip provides real-time 4D detection, identifying and tracking numerous objects simultaneously, even in extremely challenging conditions such as heavy traffic, darkness, or fog.
Unlike traditional radar solutions based around two to three transmitting antennas and three to four receiving antennas, 4D imaging radar leverages a Multiple Input Multiple Output 48-antenna array for high-resolution mapping of its surroundings. The rich point cloud data output, combined with an ultra-wide azimuth-elevation field of view, delivers detection and tracking with pinpoint accuracy, making it an ideal solution for sensing the road ahead – and behind.
