Breakthrough mm wave radar core technology
promotes the industry's " overtaking "
Disruptive technology, as a different innovation, is one of the important breakthroughs for technology innovation , and has become the focus of major innovative countries in the world to seize the initiative in development and achieve leapfrog development. In this competition, Nare Technology's "New Generation 4D Imaging Radar Based on Software Definition" project won the top ten project award in the field of disruptive technology innovation competition. What has this technology subverted? What industrial problems can be solved?
"This project is the development and application of 4D high-resolution imaging radar based on the new generation of autonomous driving platforms. It can provide high-reliability and high-resolution perception for the new generation of autonomous driving platforms, while appropriately reducing promotion costs, which will help the implementation of the new generation of autonomous driving platforms and promote the implementation of the "Medium- and Long-term Development Plan for the Automobile Industry". "When talking about this project, Zhou Kunming, general manager of Nale Technology, summarized it like this. In short, it solves key industrial problems in the field of autonomous driving, such as false alarms, missed alarms, low accuracy in complex environments, and low point cloud density of traditional millimeter-wave radars, resulting in inability to image or measure altitude, breaking through the core technical problems of millimeter-wave radar.

At present, foreign millimeter wave radar technologies have entered the transformation and upgrading stage from 3D to 4D. Because traditional millimeter-wave radars have their technical limitations, such as the inability to image point clouds and low accuracy. These indicators are usually implemented by lidar instead, but lidar is difficult to mass production and popularize in a short period of time. Therefore, finding a low-cost and reliable high-precision sensor has become the focus of the industry. The intelligent 4D high-resolution point cloud radar has become the commanding heights of global competition and is also an important window of opportunity for China to achieve lane change and overtaking.
seizes the opportunity and seizes the opportunity. Nare Technology organized a scientific research team to continue to make efforts based on the original technology. This project adopts a CMOS single-chip solution, which can continuously track dynamic/static objects, overcomes the shortcomings of traditional millimeter-wave radars that are prone to miss detection of stationary targets. While its performance is comparable to that of low-wire lidar, the product of this project is more perfect in terms of ranging and speed measurement performance and accuracy, which can achieve the replacement of traditional millimeter wave radar and low-wire lidar.
"If smaller objects (such as pedestrians, motorcycles) are mixed with larger objects (such as trucks) or are covered up, the traditional radar is unrecognizable, but our imaging radar system can identify them to determine whether they are stationary or moving, and in which direction they move, which can provide real-time data with a detection range of more than 40m." Zhou Kunming introduced that this project can automatically complete forward, backward, and turn the steering wheel without human intervention. Even in the case of visual failure, the AVP function can be fully realized by relying solely on the new generation of 4D imaging radar.
