Core Products And Features
When asked about Arbe’s core products and features, Machness explained:
Arbe develops ultra-high-resolution imaging radar chipsets and HD radar system solutions for automotive, commercial vehicles, industrial machines, defense and security applications.
Arbe’s technology is designed to help automakers, Tier 1 suppliers, and industrial OEMs build scalable perception systems for eyes-off driving and higher levels of autonomy.
Its radar delivers significantly more detail than conventional automotive radar, enabling systems to better detect, classify, and track objects in complex real-world environments.
Arbe radar solution delivers a 2,304-channel array, 10 times more than current leading alternatives, providing unparalleled resolution and performance at approximately the same size and cost.
This innovation makes it possible, for the first time, to rely on radar as a key sensor for automotive perception.
Arbe’s Phoenix Radar supports over 50,000 detections per frame, generating a point cloud denser than any other radar solution.
Machness also outlined the components behind the Phoenix Radar solution:
- A proprietary automotive-grade radar RF chipset: transmitter and receiver chips that can be combined into a 48 receiving and 48 transmitting channel system that brings higher resolution than current leading radars for reliable detection of the vehicle’s surroundings. The chipset provides best-in-class performance for channel isolation, noise figure, and transmit power at the lowest cost per channel in the market.
- An industry-first high-definition Radar Processing Chip: a processor that allows the processing of massive amounts of raw data in real time with unprecedented computational abilities, equivalent to 3Tb per second. The proprietary processor can scale from high resolution to ultra-high resolution and support the data generated from 2,304 virtual channels, which is much higher than what has been achieved on a chip in the automotive industry, while maintaining low power consumption.
- The Phoenix Radar System: Phoenix Perception Radar, with its 2K ultra-high resolution, enables an unmatched level of safety and enriches perception algorithms for advanced capabilities including Free Space Mapping, object tracking, and SLAM. No matter the speed, elevation, range, or surrounding weather and lighting conditions, Phoenix differentiates true threats from false alarms to help ensure a safe road ahead for drivers, pedestrians, and other vulnerable road users.
The Challenge Of Eyes-Off Highway Driving
When asked about some of the biggest challenges in the autonomous driving sector, Machness explained:
One of the biggest barriers in the autonomous driving industry is achieving reliable eyes-off, or Level 3, at highway speeds of 80 mph.
Key challenges include long-range detection, high-resolution object separation, very high and challenging dynamic range, free-space mapping, and large-scale system validation.
At high speeds, sensors must detect vehicles, obstacles, and road hazards far enough in advance to allow safe braking, lane changes, and other driving maneuvers.
The system must also accurately distinguish between objects that are close together, such as road debris near guardrails, while continuously identifying the drivable area.
For that, high dynamic range is critical because sensors need to detect smaller or weaker objects and minimize the interference from larger reflective surfaces nearby.
Another major challenge is validating these systems at scale.
Automakers must prove consistent performance across rare driving scenarios, dense traffic, high speeds, and difficult weather conditions before Level 3 autonomy can become widely adopted.
Arbe’s ultra-HD Radar for perception exceeds the 300-meter detection requirement while delivering the resolution needed to interpret complex highway scenarios.
Our architecture enables Arbe’s radar to measure distance and relative velocity with exceptional accuracy while resolving fine horizontal and vertical detail.
Arbe can distinguish between closely spaced objects, track multiple vehicles across lanes, identify hazards and obstacles well in advance to allow for comfortable maneuvering, and detect subtle cut-in maneuvers, effectively solving the eyes-off highway driving issue.
With Arbe’s solution, this long-standing challenge has been resolved, enabling eyes-off driving at full highway speeds.
How Arbe’s Technology Has Evolved
When asked how Arbe’s technology has evolved since launching, Machness said:
Arbe was founded in 2015 by Kobi Marenko and Dr. Noam Arkind.
Noam had a vision of a radar-based sensor for autonomous machines, which sparked the founding of the company.
It took two years to identify that the automotive market was the right vertical for our technology.
Since then, our technology has evolved from a sensor for the robotics industry to a publicly traded industry leader that is accelerating the autonomous vehicle industry by providing safe and reliable sensing.
We launched the world’s first ultra-high-resolution automotive radar system, which has since evolved into an HD radar solution with the highest channel count on the market, with superior perception at long range, elevation, and azimuth, essentially becoming the key sensor in the AV industry.
Our Phoenix Radar operates effectively in all environmental conditions, from detecting pedestrians at night and overcoming glare and light saturation, to making crucial driving decisions in adverse weather like snow, fog, and heavy rain.
Over the years, our technology has won multiple high-level awards like the CES Innovation Award twice, Informa Tech Automotive Award, Automotive News PACEpilot Innovation to Watch, Tech.AD Europe Award, the Just Auto Excellence Awards, and many others.
Arbe has also developed key partnerships, working with NVIDIA to integrate Arbe’s ultra-high-resolution radar into NVIDIA’s DRIVE Hyperion autonomous driving platform.

Total Addressable Market
When asked about Arbe’s total addressable market, Machness explained:
The market is evolving very quickly.
We continue to see new potential applications for our radar technology, while the automotive industry itself is going through a major shift, with frequent changes in OEM priorities, autonomy roadmaps, and sensing architectures.
Automotive remains our core long-term opportunity.
Third-party estimates cited in Arbe’s public filings point to a multi-billion-dollar automotive radar market, including an estimate of approximately $13.5 billion by 2032.
We believe L3 and higher levels of autonomy could represent an important part of that opportunity over time, but the timing and scope of adoption remain dependent on OEM programs, regulation, and market readiness.
Beyond automotive, we are seeing growing interest in high-performance radar for areas such as off-highway machines, commercial vehicles, agriculture, counter-drone and defense, and many other applications.
These are markets where perception in difficult conditions, such as poor visibility, dust, rain, darkness, or complex operating environments, can be highly valuable.
At this stage, we do not break out a specific TAM for each adjacent vertical, and we would not want to overstate the opportunity before these markets mature.
That said, we believe they represent meaningful potential upside to our automotive opportunity, and we are evaluating them selectively where Arbe’s technology can provide a clear advantage.
Competitive Differentiation
When asked what differentiates Arbe from its competition, Machness explained:
Arbe offers the highest channel count in the industry, which directly translates into a higher level of detail, enabling a dense 4D point cloud with range, azimuth, elevation, and velocity.
This is what enables what we believe is the best radar image quality in the automotive market.
Higher resolution and richer data help improve object separation, long-range detection, free-space mapping, camera fusion, and reduction of false alarms for the same size, cost, and power consumption as current solutions, which are limited to approximately 10% of the total channel count.
These are critical for L3 and higher autonomy, where the vehicle needs reliable perception not only in ideal conditions, but also at highway speeds, in challenging environmental conditions, and at long range.
What differentiates Arbe is not only the radar performance but the combination of performance, scalability, and automotive readiness.
Our chipset is designed to deliver high-resolution imaging radar in a form factor and cost structure suitable for mass-market deployment, while complementing cameras and other sensors in a multi-sensor perception stack.
As autonomy becomes more demanding, we believe Arbe’s technology provides OEMs and Tier 1s with a resilient perception layer that can support safer, more scalable L3 and higher autonomy.
Future Goals
When asked about Arbe’s future goals, Machness said:
Arbe’s future goals are centered on seeing our radar technology make a meaningful impact on the future of autonomy and physical AI.
We aim to deliver the level of perception needed to help autonomous systems understand and navigate the real world safely, reliably, and at scale.
A key part of our vision is to help democratize autonomy.
By offering advanced sensing capabilities through a radar-based solution that can be more affordable and scalable than current-generation sensing technologies, Arbe can help make higher levels of autonomy accessible across a broader range of vehicles, platforms, and industries.
At the same time, we are focused on scaling adoption of our ultra-high-resolution radar chipsets with automotive OEMs and Tier 1 suppliers, supporting the transition from development programs to mass production, and continuing to grow in key markets.
We are also expanding Arbe’s radar technology beyond passenger vehicles into high-value verticals such as robotaxis, robotrucks, defense, smart infrastructure, and off-road applications, where reliable perception can create significant value.
