For what is 4D imaging radar, some friends may not be very clear, here is a brief introduction:

4D imaging radar can clearly detect and distinguish different objects at a distance of 300 meters (picture from geoweeknews)

4D Imaging Radar is a breakthrough technology that extends the capabilities of radar from measuring distance, speed, and horizontal azimuth to cover Range, Azimuth, Elevation, in any lighting or weather condition. ) and the measurement of relative velocity, in other words, 4D imaging radar can sense small objects, stationary objects, or laterally moving obstacles that cannot be recognized by traditional millimeter-wave radars.
1. High resolution, strong perception, can distinguish false alarms

An important reason why Tesla gave up millimeter-wave radar is that the resolution of millimeter-wave radar is low, for example, it cannot distinguish bridge holes, billboards, etc., and it is easy to false alarm. However, 4D imaging radar can achieve 1° lateral resolution & 2° longitudinal resolution, wide field of view, and long, medium and short range automotive radar sensor detection technology, enabling it to detect hundreds of objects in real time, putting real threats Distinguished from false alarms, the presence or absence of speed is unaffected by its altitude, proximity, size, or surrounding weather and light conditions.
 
High-sensitivity tracking technology identifies objects individually, such as pedestrians, bicycles and motorcycles, even if they are obscured by vehicles or stationary objects. Continuous perception of direction, speed and speed to achieve high-definition situational awareness of autonomous vehicles at all levels.
2. Ultra-long detection distance, up to 300 meters

Because of its unique antenna chip design, 4D millimeter-wave radar can obtain point cloud data, and the detection distance of 0.5~300m can easily meet the needs of autonomous driving at this stage.
3. Applicable to various levels of vehicle autonomous driving or various vehicle categories

The 4D imaging radar is fully customizable, with a modular design, suitable for various levels of vehicle autonomy or various vehicle classes. From L2 to L5, long-range front end to mid-range corner and blind spot detection technology, the full-featured imaging radar features a modular design that allows OEMs the freedom to set resolution, range, field of view and capabilities to suit a variety of design specifications and cost requirements.

In addition, 4D imaging radar has huge advantages compared to the cost pressure of LiDAR, which is more than a thousand dollars.
