What are the advantages of 4D imaging radar?
1. High-resolution recognition
Traditional millimeter-wave radar cannot distinguish between vehicles and people gathering together, and may even identify them as one object. The 4D millimeter wave radar can distinguish people, cars and bicycles through different energy densities and high resolutions.
2. Real-time monitoring of obstacles
Whether it is day or night, sunny or rainy, 4D imaging radar can provide highly detailed environmental images and detect various obstacles in real time, which can Determine if they are moving and in which direction, and provide real-time situational data and alerts to the vehicle.
3. Beyond visual range perception
The multipath processing capability of 4D imaging radar enables it to have beyond visual range perception function. Through the electromagnetic waves transmitted from the bottom of the vehicle in front, the 4D imaging radar can "see" the status of the vehicle in front, or even the vehicle in front of it. When the vehicle in front decelerates suddenly, the vehicle ahead can predict the movement of the vehicle ahead to prevent a series of rear-end collisions.
Ultra-long-distance detection
Compared with traditional millimeter-wave radar, 4D imaging radar can provide a viewing angle range of 300 meters and ±50°. It is the device with the longest detection range and the earliest detection of danger among all sensors, and can introduce lidar and cameras into the area of ??interest to improve driving safety.
4. More accurate height recognition
It is very easy for traditional millimeter-wave radar to mistakenly trigger the brakes when following a car under a height limit pole, because it cannot distinguish between a stationary height limit pole and a moving vehicle. . The 4D imaging radar has height information and can easily identify that the vehicle in front passes under the height limit pole, thereby ensuring the smooth passage of the vehicle.
In addition, 4D imaging radar can accurately identify special-shaped, slow-moving, and stationary obstacles through point clouds. In daily driving scenarios, complex obstacles such as special-shaped construction vehicles, cones, and roadblocks beside high-speed guardrails will challenge the recognition capabilities of intelligent driving vehicles. 4D imaging radar makes up for the shortcomings and provides safer intelligent driving travel. Assure.
Such a high-tech device that sounds like it is actually not far away from us. SAIC’s R Auto has debuted the most cutting-edge 4D imaging radar on its upcoming flagship model ES33. In addition, the car is also equipped with a bunch of rich equipment. Devices, including lidar, high computing power platform and SOA services. I believe that with their blessing, ES33 will not only be technologically fun, but also safer and more secure.
