Autoroad's 77 GHz short-range automotive mmWave radar is mounted at the two rear corners or all four corners of the vehicle body, detecting about 0.5 to 100 m with a 3T4R architecture. Compared with 24 GHz, it offers higher accuracy and a smaller size, supporting blind-spot detection (BSD), lane-change assist (LCA), rear collision warning (RCW), door-open warning (DOW) and front/rear cross-traffic alert (F/RCTA). It is certified to ISO 17387, Korea KC and Vietnam MIC.
