Powered by Calterah’s Dubhe SoCs, the in-cabin radar reuses the UWB digital key anchors to lower system costs. It offers a wide coverage of three seating rows, strong penetration, and low power consumption. The radar can accurately detect vital signs such as breathing and heartbeat, penetrating obstacles including seats and clothing. It supports various in-cabin monitoring scenarios, enabling features such as life presence detection, child presence detection, intrusion detection, and occupancy detection.
