At the Smart High-speed Technology Development Forum held at the 24th China Expressway Informatization Conference from July 27 to 28, Huawei officially released a new generation of ultra-long-distance high-precision millimeter Wave traffic radar ASN850 and fusion perception engine SNE800.
Huawei said that in the intelligent transportation system, the radar will be an important roadside sensing unit because it can detect and perceive traffic flow all-weather without being affected by weather and light. In addition, with the continuous progress and development of industry technology, the traffic perception system is moving from “perception at the node” to “full-time global perception in the road network”.

In this context, traditional traffic radars expose problems such as short detection distances, many blind spots, large demand for poles, discontinuous cross-station trajectories, and poor detection and recognition accuracy in complex scenarios.
In this regard, Huawei has developed a new generation of ultra-long-range high-precision millimeter-wave traffic radar ASN850. The radar adopts two industry-leading technologies, 5G Massive MIMO large-scale antenna array and super-resolution algorithm, and successfully achieves a two-way 1,000-meter, 10-lane ultra-long distance. Distance-free coverage, which means it will reduce pole station deployments by more than 25%.
In addition, the fusion perception engine SNE800 based on the intelligent edge computing platform introduces the principle of continuous coverage lossless switching of wireless base stations for the first time and uses single-pole Ray-vision fitting, cross-station radar fitting, and occlusion/cross-pole fitting technology to achieve all-weather trajectory continuity, and the target accuracy rate reaches 95%.
At the same time, the fusion perception engine SNE800 has a recognition rate of more than 95% in complex scenarios such as large vehicles covering small vehicles, vehicles with hazardous chemicals, throwing objects, congestion, and traffic accidents.
Yang Xi, vice president of Huawei’s wireless product line, said that in the upcoming 5.5G era, the integration of wireless sensing and communication technologies will bring more new scenarios and applications beyond the traditional, and Huawei will work together with the industry. Accelerate the digital and intelligent transformation of the industry.
