摘要：
A radar sensor system (10) and a method of operating the radar sensor system (10) for detecting an occupancy in an interior (34) of a vehicle (32) and with vital sign monitoring is provided. The radar sensor system (10) comprises a radar transmitting unit (12), a radar receiving unit (18) and a signal processing and control unit (26). The method includes at least steps of transmitting (60) a radar wave towards a scene within the vehicle interior (34), receiving (62) at least one radar wave that has been generated by reflection of the transmitted radar wave (16), - decomposing (64) the received at least one radar wave (22) into range, Doppler and angular information, quantifying and tracking (68) a movement in each region of interest (38, 40, 42) by angular gating and range gating, detecting (78) and monitoring vital signs of occupants (28, 30) in each region of interest (38, 40, 42), and determining (84) whether quantified and tracked movements in the scene are related to an occupant (28, 30) or to external or internal disturbances, based on a fulfillment of at least one predefined condition concerning the quantified and tracked movements and/or the detected and monitored vital signs.
