TCM873 is an 80 GHz traffic flow statistical millimeter wave radar module independently developed by Hunan Nanoradar Technology Co., Ltd. The module can provide multi-target tracking information between large, medium and small vehicles, non-motorized vehicles and pedestrians traveling in both directions within a range of 500 meters, including real-time information such as ID, distance, speed, azimuth and status of all targets. At the same time, it also supports traffic flow statistics, which can output information such as vehicle spacing, occupancy, queue length, congestion and so on. Among them, the accuracy of congestion flow statistics reaches 90%, and the accuracy of flat peak flow statistics reaches 95%.
80GHz MMW radar
The product can be applied to high-speed traffic monitoring, intersection monitoring, intersection detection and other application scenarios.
