Israeli startup Arbe, which has raised $55 million so far to develop a 4D imaging radar chipset, has today announced exclusively through EE Times that it’s now launched its imaging radar processor chip as a part of the chipset.

The company said this is often the primary automotive-grade (AEC-Q100) dedicated imaging radar processing chip. The patented chip is capable of processing the data generated by 48 receiving channels and 48 transmitting channels, generating 30 frames per second, meeting automotive power constraints. This, it said, is above has ever been achieved on an automotive radar processing chip, while doing so in an “efficient and cost-effective manner”.

Additionally, the processor can scale from high resolution to ultra-high resolution and support over 100,000 detections per frame. consistent with Arbe, this ability to process such a high channel count provides unparalleled performance and safety to the automotive market. The radar processing chip enables the mixing of smart detection algorithms, clustering, post-processing and SLAM (simultaneous localization and mapping) into the chip. The processor is meant in accordance with the international standard for functional safety (ISO 26262), and therefore the processor enables ASIL B (Automotive Safety Integrity Level) qualification for the radar chip.

Arbe’s chipset produces detailed 4D images, separates, identifies, and tracks objects in high resolution in both azimuth and elevation on top of the range and Doppler resolutions, during a long-range and a good field of view, and complemented by AI-based post-processing and SLAM. the corporate has also developed its own proprietary millimeter-wave automotive-grade radar RFIC chipset that has a transmitter chip with 24 output channels and a receiver chip with 12 input channels. employing a 22FDX FDSOI CMOS process, Arbe’s RF chipset is meant to support TD-MIMO with strong performance characteristics for channel isolation, noise, and transmit power.

The CEO of Arbe, Kobi Marenko, said, “The amount of processing capabilities that we incorporated on our radar chipset solution is one that has never been achieved before in automotive radar. Our technology will bring the security of vehicles to a replacement level with low power and low cost. We are excited to ship the processer chip to Tier 1 customers as a part of a chipset solution that supports their next-gen radar system developments.”

The company said its processor provides more processing power, low latency, and low power while cutting the value to implement a secure radar solution. We delved into these performance claims a touch more to qualify them.

First, on processing power, Arbe said the processor is capable of processing 30 Gbps of knowledge, representing a virtual array of over 2300 virtual channels. Today most radars are processing but 10% of the bandwidth and typically up to 12 virtual channels. With reference to the latency claim, Arbe said 30 fps provides real-time frames every 33 ms, which enables a maximum latency from the top of some extent cloud frame until it’s received at the most ECU of 34ms.

What about power consumption? Arbe said the chip is made to supply typical power consumption of but 4W. Since most of today’s radar power consumption is around 10W-20W, the corporate said it’s obtaining two orders of magnitude performance at approximately an equivalent power budget. On the value claim, the corporate said, “We are at the lower cost compared to the new radars of 12×16. We present an option of 10x performance for an equivalent price as of today’s long-range radars.”
