1. What is Lynx and how does it differ from traditional corner radars?
Lynx is a Surround Imaging Radar designed for corner and back installation. Unlike traditional corner radars, which have low resolution and are limited to basic tasks like blind-spot alerts, Lynx provides high-resolution imaging, long-range performance, and a wide field of view. This allows it to be included in sensor fusion and perception, helping the vehicle identify stationary objects and map drivable “free space.”
2. How does Lynx complement the Phoenix 48×48 Perception Radar?
While Phoenix serves as the “gold standard” primary front/rear sensor, Lynx is its ultimate partner. When installed together, they can be fully synced for unified perception and interference avoidance. This creates a harmonious 360-degree safety cocoon around the vehicle, ensuring that multiple radars work together to understand the driving environment coherently.
3. Why are other sensor types (LiDAR, Cameras) insufficient for corner applications?
Every other sensor has a significant drawback:
4. What are the key technical specifications of Lynx?
Lynx packs massive performance into a small form factor (77x67x38 mm):
5. How does Lynx assist with complex maneuvers like highway merging?
Merging into fast-moving highway traffic requires sensing high-speed vehicles coming from the back and sides. Lynx provides the long-range detection and “Doppler” (instant speed) data needed to track these vehicles accurately, allowing the car to make safe lane changes and merges that cameras or basic radars would struggle to manage.
6. Can Lynx help a vehicle navigate a busy T-junction or intersection?
Yes. Navigating intersections involves detecting lateral (side-to-side) traffic and vulnerable road users like cyclists. Lynx’s wide 140° field of view and high resolution allow it to detect exact object boundaries and create a reliable “Free Space Map,” making unprotected turns significantly safer.
7. Is Lynx suitable for ADAS or only for fully autonomous vehicles?
Lynx is optimized for both. While it is a powerhouse for L2+ and higher autonomy, it can also be used as a standalone front-facing solution for basic ADAS applications. Its 12×24 RF channels represent a significant upgrade over existing ADAS sensors, providing a higher level of safety for any vehicle class.
8. What does “Future-Proofing” mean in the context of Lynx?
Arbe designed the Lynx processor to be open and flexible. OEMs can add their own current and future algorithms—such as trackers or super-resolution—directly onto the radar processor without needing additional hardware. This allows the vehicle’s perception to evolve through software updates throughout its lifecycle.
9. How does Lynx handle “radar interference” in congested environments?
When Phoenix and Lynx are installed together, they utilize unified perception and interference avoidance technology. This ensures that the various radar units on the vehicle do not jam each other, maintaining a clean and accurate data stream even when the environment is “noisy” with other radar signals.
10. Why is Lynx considered a “paradigm shift” for the industry?
Lynx proves that high-performance imaging doesn’t have to be limited to the front of the car or to luxury price points. By delivering perception-level data in a small, affordable package, Lynx enables 360-degree safety for the mass market, accelerating the transition to a world with zero road fatalities.
Say Hello to Lynx Surround Imaging Radar
Due to limited range, inadequate compute power, and low resolution, today’s corner radars do not provide imaging, and therefore are not included in sensor fusion and perception. Used only for basic driver assist features like side blind spot alert, cross traffic alert and tracking of dynamic objects, corner radars provide input to help the vehicle decide how to respond. However, for challenges like identifying stationary objects, determining object size and shape, dealing with cluttered dense environments, or making decisions about whether a space is drivable or not, today’s corner radars fall short.
That changes now.
Arbe is proud to introduce Lynx Surround Imaging Radar, designed primarily for corner and back installation, Lynx complements Phoenix 48*48 Perception Radar to deliver a 360 degree view around the vehicle, and offers a full set of benefits with an affordable price– true long range performance, high resolution, small form factor, and very wide field of view. It effortlessly outperforms the current industry 3*4 corner radars and even the leading 12*16 long range radars on the market, providing future-proofing perception and superior imaging capabilities that are vital for true safety and autonomous driving.
Arbe’s Phoenix sets the gold standard for imaging radars in the industry. It’s 48*48 channels offer best-in-class performance, ultra-long range in the front center and back, and it is able to act as a primary sensor within the sensing suite. To support Phoenix, Lynx both overlaps and expands on these capabilities.
Lynx is optimized for ADAS and L2+ and higher autonomy, and acts as the ultimate complement to Phoenix. When installed together, Phoenix and Lynx can be fully synced, with unified perception and interference avoidance that ensures the multiple radars operate together harmoniously. While Lynx will most often be installed as a corner radar for L2+ and higher autonomy, it can also be used in the back for some applications, and even in the front if intended for ADAS alone.
Everyday driving tasks frequently involve a level of complexity that most surround sensors are not equipped to handle, such as navigating a T-junction, or merging onto a highway, but Lynx handles that with ease. Lynx can even be life saving, when emergency steering or braking is needed.
Importantly, Lynx is the industry’s first effective and affordable sensing solution to cover 360° around the vehicle while achieving enhanced safety. Every other leading sensor type suffers from at least one significant disadvantage.
A reliable and affordable alternative that provides both redundancy and data diversity is critical for automotive-grade safety, and for rolling out autonomous features. Lynx delivers both: effective sensing in all environmental conditions, and data that optical sensors lack, like Doppler, long range, depth perception, and more.
As a high resolution surround sensor, Lynx is critical for a wide range of advanced autonomous and ADAS applications. The ability to make unprotected turns in intersections or junctions detecting lateral traffic, merge into a highway while avoiding fast traffic coming from the back and sides, change lanes on fast moving roads by mapping the adjacent lanes, or reverse from a parking spot onto the street– among many other use cases – all require long range, high resolution detection of exact object boundaries, the ability to create an image of the vehicle’s surroundings at a wide field of view, and free space mapping. Lynx accomplishes all of these with its high channel count and unmatched performance.

For most existing ADAS/L2+ features, Lynx, with its 12×24 RF channels, is by itself a significant upgrade. However, it is the imaging and perception capabilities in 360 degrees that Lynx enables that are critical for autonomous driving in urban environments, challenging intersections, heavy VRU traffic, and more. Autonomous technology may not be ready for the mass market today, but in order to develop and roll out these advanced features, OEMs need to collect massive amounts of data in as many real life scenarios as possible, with the right sensors. Lynx allows access to the quality data OEMs need, powering the roll out of these software-defined features to existing and new customers. Moreover, the cycle of data collection, feature development, and software roll out enables perception to continually evolve and add value throughout the vehicle lifecycle. Arbe has designed the Lynx processor so that OEMs will be able to add their current and future algorithms onto it – from a tracker to super resolution (or any post processing they desire!) – without the need for additional hardware. By integrating Lynx into their sensor suite, automakers are in effect “future proofing” their vehicles, positioning themselves at the head of the race to retail autonomy.
Lynx Imaging Radar represents a paradigm shift, both for the role radar will play in ensuring safety and as part of the overall autonomous sensor suite. The best complement to the Phoenix Perception Radar, with surround imaging and perception capabilities, Lynx is the powerhouse support that will accelerate the autonomous revolution.
