Review of wonderful speeches

All day on June 21st

Millimeter wave radar session

The research on vehicle mounted millimeter wave radar began in the 1960s, mainly conducted in developed countries such as Germany, the United States, and Japan. The early development of vehicle mounted millimeter wave radar was slow, but with the advancement of microelectronics technology, miniaturization and integration of products have become possible, and the development process of radar has begun to accelerate. After the 21st century, with the increasing demand in the automotive market, the industry has entered a stage of vigorous development and will continue to accelerate its penetration in the future.

The heavyweight speaker who first appeared at the millimeter wave radar special session on the 21st came from a leading global analysis institutionYole Group, Radio Frequency Technology&Market Analyst, Mr. Rapha ë l da SilvawithMapping Out the Latest Trends in Automotive Radar MarketProvide a fascinating analysis of the theme.

The evolution of millimeter wave radar to today's 4D imaging radar is a progressive development supported by new generation hardware (sensors and computing) and software. At the same time, it introduces the global OEM layout in the L3 level autonomous driving field and the safety, concentration, and innovation in automotive technology. It predicts revenue by radar type from 2023 to 2029 and deeply explores the dynamic prospects of automotive radar technology.

Musk once said that high-resolution radar vision solutions would be better than pure vision, and 4D imaging radar, with its long-distance, all-weather, instantaneous accurate speed detection, reliable and low-cost characteristics, is gradually recognized as a breakthrough for ADAS.

The invited guests who will appear later areMr. Niu Li, CEO of Beijing Aotu Technology Co., Ltd., brings a topic titled "The Challenge of Imaging Millimeter Wave Radar"A wonderful speech. Mr. Niu pointed out that 4D imaging radar has extremely high data efficiency. Compared to LiDAR, it can achieve the same or even better perception effect with about 1% of the points, greatly reducing the demand for central computing. Achieve better ADAS performance with limited computing power. However, it also faces challenges such as point cloud density, noise level, velocity blur, weak target detection distance, dynamic range of angle measurement, height measurement, structural heat dissipation, computing power, and height resolution.

It states that Altos Radar is a startup company deeply involved in 4D imaging millimeter wave radar. Focused on creating a new generation of 4D imaging millimeter wave radar with high performance, high reliability, and low cost, empowering high-level assisted driving and fully autonomous driving, bridging the perception gap in the commercialization of autonomous driving, and providing important cornerstone products for its true implementation. Aotu Technology's solution is the only non FPGA 12TX-16RX solution in the world, with comprehensive sensing performance comparable to LiDAR @~1/10 cost and ready for sample testing at any time.

At present, the hot topics in the AI semiconductor market include AI/NPU/GPU processors (computing power innovation, chip energy consumption) and microcontroller MCUs (price cost). However, precise perception of environment and events has become a technical barrier and bottleneck in many situations, making it difficult to implement AI solutions and requiring intelligent fusion perception to solve problems.

The third invited speaker for the millimeter wave radar special session is fromMr. Jiang Hong, CEO of Shanghai Yugan Microelectronics Technology Co., Ltd., discusses the "Yugan Micro Multi Sensor Fusion Perception Solution"Systematically elaborated on the theme. Mr. Jiang stated that Yugan Microelectronics' products include multi-sensor (radar vision) fusion perception processor chips. The product integrates FPGA reference design solutions and provides reference designs for sensor fusion perceptrons based on FPGA chips, combined with current market hot demand, to quickly promote "multi-dimensional pixel technology" to the market.

Yugan Micro focuses on "perception intelligence" chips and solutions, committed to launching multi-dimensional (visible light vision/infrared vision/millimeter wave radar 4D perception, etc.) perception data fusion algorithms and lightning vision perception chip and lightning vision fusion technology solutions, providing unprecedented target and environment "multimodal semantic" accurate information perception technology for autonomous driving and machine vision, helping car companies overcome the threshold of L3/L4 level intelligent driving perception technology.

In November 2021, Ambarella acquired Oculii and began to enhance its imaging radar technology after the success of its vision chip. To be precise, it is to integrate the 4D imaging radar algorithm with a large computing power domain control chip to create a new generation of 4D imaging radar. At the same time, vision and radar perception are pre fused at the pixel and point cloud levels, making the integration of lightning and vision truly possible.

The next speaker will be fromMr. Qi Jianjun, Vice President of Marketing at Anba Semiconductor, presented "Central Domain Control Radar Leading 4D Imaging Radar into a New Era"To give a wonderful introduction to the theme, it first points out that the Anba chip paired with the Oculii algorithm creates a new mode of central domain control radar. Oculii's 4D imaging radar technology uses virtual artificial intelligence (AI) software, which can significantly improve the resolution of the radar, up to 100 times. Compared to traditional millimeter wave radar, Oculii can improve angular resolution through dynamic and adaptive waveform, and software, avoiding the cost and power consumption of hardware antennas from doubling.

Subsequently, it introduced the exponential improvement in performance achieved by Ambarella's central domain control 4D imaging radar. It can not only perform centralized processing on raw radar data, but also perform deep low-level fusion with other sensor inputs. The integration of Ambarella and Oculii has achieved significant results in software and system integration. The OculiTM Centralized 4D Imaging Radar system is a complete end-to-end solution that controls and optimizes radar data through CV3-AD SoC, taking radar system performance to the next level.

4D imaging radar has performance similar to Lidar, all-weather and speed measurement capabilities, superior to Camera/LiDAR, moderate price, sparse data, and reduced requirements for data transmission and processing, making 4D imaging radar have excellent cost advantages.

Invited by the conference to attendMr. Jiang Jun'an, President of Beijing Xingyidao Technology Co., Ltd., discusses the new technologies and applications of 4D millimeter wave imaging radarElaborated in detail on the development direction of 4D millimeter wave imaging radar. It first introduces the development trend and market expectations of autonomous driving sensors, and makes market estimates on the cost of autonomous driving sensors and 4D imaging radar (including ECU). It discusses the advantages of perception fusion systems mainly based on 4D imaging radar, which can be used for spatial modeling and deep learning to achieve target recognition. It points out that 3D depth of field is necessary for high-level autonomous driving technology, which helps to improve spatial prediction and target recognition through accurate position information.

It is explained that sparse signal processing refers to the signal processing technique of extracting as few sampled data as possible from raw data containing a large amount of redundant information, and effectively approximating and recovering the original signal. Next, it elaborates in detail that as a benchmark enterprise in domestic 4D imaging radar technology, Xingyidao adopts unique sparse signal imaging algorithms and antenna array technology to achieve dense point cloud imaging effects on the surrounding environment, enabling millimeter wave radar to obtain three-dimensional modeling capabilities, new target recognition and path planning capabilities, and thus has the possibility of replacing laser radar.

Behind the rapid growth in the scale of 4D imaging radar boarding, it must have been verified by the car manufacturer's system, ensuring that the boarding effect meets expectations and satisfies the user's experience. Although 4D imaging radar increases the number of virtual channels through chip cascading, the traditional TDMA (Time&Division&Multiple&Access) transmission method cannot solve the problem of transmitting all Chirps within the radar perception cycle. The sidelobe suppression is insufficient, which can easily lead to ghosting. The dynamic range of radar signal processing is insufficient, making it impossible to detect small and weak targets. At the same time, in the productization process, multiple measurement algorithms are selected to optimize efficiency, and the processor is chosen to balance cost and computing power. Each link will affect the final product performance indicators, often resulting in point clouds. The results are not ideal due to limited quantity, poor quality of point cloud measurements, and numerous false targets.

The first keynote speaker for the afternoon session on millimeter wave radar was fromMr. Feng Hao, Vice President of Saien Lingdong (Shanghai) Intelligent Technology Co., Ltd., presented his paper on "Reshaping the Core Value of Millimeter Wave Radar in Intelligent Driving with 4D Imaging Radar"Answer questions and clarify doubts about the topic.
