Abstract
A radar sensor system and a method for detecting an occupancy in an interior of a vehicle and with vital sign monitoring. The radar sensor system includes a radar transmitting unit, a radar receiving unit and a signal processing and control unit. The method includes: transmitting a radar wave towards a scene within the vehicle interior, receiving at least one radar wave that has been generated by reflection of the transmitted radar wave, decomposing the received radar wave into range, Doppler and angular information, quantifying and tracking a movement in each region of interest by angular gating and range gating, detecting and monitoring vital signs of occupants in each region of interest, and determining whether quantified and tracked movements in the scene are related to an occupant or to external or internal disturbances, based on a fulfillment of at least one predefined condition concerning the and/or the detected vital signs.
