The latest news on 4D millimeter wave radar: Huawei | Chuhang | Uhnder | Xingyidao | Mu Niu | Furui Zhixing

4D imaging radar also belongs to millimeter wave radar and is the evolution of traditional millimeter wave radar. In terms of detection range, traditional millimeter wave radar can only detect three dimensions: distance, orientation and speed.

4D millimeter-wave radar adds height-dimensional data analysis of targets on the basis of the original distance, orientation, and speed. It can realize information perception in four dimensions of "3D + speed" and can effectively analyze the outline, category, and behavior of the target.

Qiankun has brought newly upgraded "Qiankun ADS", "Qiankun Car Control", "Qiankun Car Cloud" and other solutions.

The first high-precision 4D millimeter-wave radar in China comprehensively improves target detection and environment modeling capabilities. It can see further, with a 35% increase in ultra-long range, more accurate sight, a 4-fold improvement in high accuracy, and a 65% reduction in latency.

2. Chuhang Technology’s 4D millimeter wave radar debuted at the Beijing Auto Show

Chuhang Technology debuted at the 2024 Beijing International Auto Show with its latest product and technology lineup, displaying a full range of fifth-generation iterative mass-produced radar products that have been replaced by localization, as well as sixth-generation innovative radar products and technologies.

As the first domestic millimeter-wave radar company with TI, NXP, and self-developed national solutions, it promotes global market layout. It also takes the lead in formulating new industry standards and continues to consolidate Chuhang with highly competitive technical strength. Science and technology has moved from "domestic substitution" to "domestic transcendence" in the industry's leading position.

3. Uhnder launches the first 4D digital imaging radar chip suitable for the wider automotive market

April 24, 2024, Shanghai, China - Uhnder, a leading company in digital imaging radar chip technology, announced the launch of a new imaging radar solution S81. The S81 is a highly integrated single-chip solution that supports up to 96 MIMO channels and is based on leading digital code modulation (DCM) to provide a more cost-effective 4D digital imaging radar solution for the wider automotive market.

In the field of autonomous driving, 4D imaging radar has attracted much attention for its excellent safety performance. However, due to technical complexity and high cost, this technology is currently only used in high-end models. To address this issue, Uhnder has developed the S81, the first imaging radar solution for the wider automotive market, allowing more automotive and radar manufacturers to enjoy the safety benefits of 4D imaging radar.

4. Xingyidao unveiled its vehicle-mounted forward long-range millimeter wave 4D imaging radar ALRR300 at the Beijing Auto Show

On April 25, 2024, the 18th Beijing International Auto Show officially kicked off. Beijing Xingyidao Technology brings vehicle-mounted forward long-range millimeter wave 4D imaging radar ALRR300, vehicle-mounted short-range millimeter wave radar ASRR220, vehicle-mounted forward medium-range millimeter wave radar AMRR280, vehicle-mounted short-range millimeter wave radar ASRR100, vehicle-mounted forward medium-range millimeter wave radar Radar AMRR200, vehicle forward medium-range millimeter wave radar AMRR210, and traffic radar AITR300 were unveiled at this auto show.

On the first day of the auto show, the atmosphere at the Xingyidao booth was lively. BAIC Zhijia, Sony solution provider, Wuling New Energy Xiaomi Motors, Panasonic, Huawei, Jiazi Guangnian and many other OEMs, solution providers, media platforms, investment institutions and Xingyidao Together we will discuss the technical implementation and application of 4D imaging technology.

5. Muniu 4D imaging radar I79 and Horizon Journey 6 collaborate to meet the mass production needs of mid-to-high-end full-scenario intelligent driving.

On April 24, [Horizon], a leading smart driving technology company, released the latest Generation Journey 6 and a new high-end smart driving solution. Muniu Technology's 4D imaging radar I79, combined with Horizon's Journey 6 released this time, jointly meet the mass production needs of mid-to-high-end full-scenario intelligent driving, and jointly help intelligent driving to advance.

In order to ensure the reliability and safety of mid-to-high-end sensing solutions, Muniu Technology has established an internationally standardized testing process, and has successively passed the highest level ASIL-D functional safety process certification of ISO 26262, ISO/SAE 21434 automotive network security products, and Multiple international authoritative certifications from five countries.

Muniu Technology began to lay out 4D imaging radars as early as 2018. Two models have achieved large-scale mass production and many are under development. The product performance and maturity have been verified by many market-side customers and are at the leading level in the industry. In terms of mass production efficiency, it is only It takes 20 seconds to automatically produce a single 4D imaging radar.

The I79 used with Journey 6 this time is the ultimate cost-effective solution launched by Muniu. It solves many problem scenarios of traditional millimeter wave with limited cost increase. I79 has been fully optimized in waveform design, aperture array, transceiver channels, algorithm architecture, computing efficiency and anti-interference. After being integrated with the front camera, it can realize L3 level NOA system functions (auto-assisted navigation driving) such as autonomous on- and off-ramps and intelligent lane changes.

6. Furui’s smart pre-departure integrated sensing solution made its debut at the Beijing Auto Show

On April 25, the 2024 Beijing International Auto Show opened grandly. Fului Zhixing publicly demonstrated its self-developed perception fusion solution for the first time. This solution is developed based on Horizon Journey® 6 and uses a combination of 4D millimeter wave radar + camera to replace lidar. While providing a sensory supplement to the pure visual solution, it also opens up a safer and more cost-effective new path for intelligent driving for the industry. .

After long-term development, the current stage of the autonomous driving industry has put forward higher requirements for perceptual performance. Common target detection algorithms are difficult to give accurate outlines of obstacles, and cannot effectively solve the long-tail problem of target detection; pure visual perception solutions are cost-effective, but the overall robustness of the perception system still needs to be improved; and the integration of cameras and lidar Although the solution has the advantage of good robustness, the market still needs to further reduce the cost of sensor hardware. Based on the above-mentioned pain points, Forui Intelligent Technology proposed a front-end fusion solution of 4D millimeter wave radar and camera to achieve optimal performance and cost.

The effect of Furui Intelligent Travel Perception Fusion Solution

The perception fusion solution for this public demonstration was developed by Forui Intelligent Technology and uses a completely independently developed unsupervised neural network model. It can achieve universal obstacle detection without relying on a large amount of manual annotation data, improving the user experience of active safety functions. At the same time, combining the latest 4D millimeter-wave imaging radar with 6 transmitters and 8 receivers from Forui and Horizon’s latest generation journey platform can allow autonomous driving solution providers to provide sensory redundancy for pure visual solutions without changing the original technical architecture. and enhancement, realizing the complete replacement of lidar, opening up a new path for safer and more cost-effective intelligent driving, and further meeting the needs of OEM customers and intelligent driving users to reduce costs and increase efficiency.
