[0002] With the continuous breakthroughs in radar technology and the development of industry technology, millimeter-wave radar systems are constantly developing towards more point cloud data, which also makes the radar interface a bottleneck. The CAN-FD interface in traditional radars can no longer meet the transmission of more point cloud data. The number of traditional radar point clouds is around 128, and the latest generation of 4D cascade imaging radar data point clouds are around 500-1024. More point cloud data means that a larger data bandwidth is required. A data interface that can take into account both high bandwidth and high stability, the coaxial link based on GMSL is a solution, but the cost is relatively high.

[0003] With the rapid development of automotive millimeter-wave radar technology, the in-vehicle Ethernet interface is the best choice, which takes into account the bandwidth while meeting the high reliability requirements of the in-vehicle network. As the body network is also constantly changing, upgrading and optimizing, how to design a suitable data collection for in-vehicle product debugging has become a rigid demand. Utility Model Content
