A seating system for a vehicle includes a vehicle seat, a first Doppler radar sensor positioned within the seatback and aligned with the heart of a person sitting in the seat, a second Doppler radar sensor positioned within the seatback and offset from alignment with the heart, and a controller. The first sensor transmits a signal toward the heart and receives a first reflected signal as modulated by heart movement and by a random motion of the person. The second sensor transmits a signal toward an anatomical location of the person offset from the heart and receives a second reflected signal as modulated by the random motion of the person. The controller generates a biometric signal corresponding to the heart movement, without random motion artifacts, based on a difference between the reflected signals whereby the biometric signal is indicative of cardiac information of the person.
