Calterah’s automotive multi-mode mmWave radar reference design is a system-level design supported by the Alps family of the 77-GHz auto-grade and fully-integrated mmWave radar SoC chips. It integrates the functions of forward-looking radar and corner radar and offers 3 operation modes of Long-Range Radar (LRR) Mode, Medium-Range (MRR) Radar and Short-Range Radar (SRR) Mode. This reference design enables real-time detection of objects in front of and beside a vehicle and collection of their information including range, relative velocity, azimuth, etc., thus satisfying the demand for features like adaptive cruise control (ACC), automatic emergency braking (AEB), forward collision warning (FCW), blind spot detection (BSD), etc.
