Applications

Forward-Looking Radar

Enabling Adaptive Cruise Control (ACC), Forward Collision Warning (FCW), and other ADAS functions

Calterah's forward-looking radar solution, developed based on the Alps-Pro mmWave radar SoC, offers outstanding detection performances and meets the requirements of forward-looking radar for L2/L2+ ADAS systems, enabling functions such as Adaptive Cruise Control (ACC) and Forward Collision Warning (FCW). The Alps-Pro forward-looking radar solution offers long-range mode (LRR) and medium-range mode (MRR), featuring powerful capabilities in range detection, real-time velocity measurement, azimuth and elevation measurement, angular resolution, and target depiction, helping vehicles to “see” farther and more accurately, thus enhancing vehicle active safety.
