Vital Sign Detection Radar

The Chuhang Technology “automotive-compatible platform” developed 60GHz vital sign detection radar covers the whole cabin area with a compact design, and low cost & low power consumption. It has a false alarm rate lower than <1% and missing alarm rate of zero. The radar can realize the rear occupant alert (ROA) for the second row of the back seat, vital sign detection for the third row of the back seat, and DMS for driver’s breathing & heart rate monitoring.

Application scenarios


Rear Occupant Alert (ROA) The millimeter-wave radar installed on the roof senses the whole cabin. It detects and classifies target objects and monitors the number of people in the cabin through vital sign detection.

Child Presence Detection (CPD) The system detects children or pets in the cabin and outputs the warning information to the driver to prevent children or pets from being left in the cabin.

Seat Occupant Detection (SOD) The system detects which seats are occupied and sends the occupant information to the vehicle as the basis of secondary development of other functions.


Driver Monitoring System (DMS) The system monitors the breathing and heat rates of the driver and triggers alarms for driver’s vital sign anomaly.

Air bag improvement The millimeter-wave radar imaging evaluates the size of a target, and identifies the target as an adult or a child to optimize the air bag configuration.
