Claim:
1. A radar apparatus for detecting a life-sign of a subject, comprising: a transmitter system including a single radar unit for emitting a multiple number of transmission electromagnetic beams, wherein a first transmission electromagnetic beam is directed directly to a chest and/or abdomen of a subject, and wherein a second transmission electromagnetic beam is first directed to a redirector and redirected in a different direction from that of the first transmission electromagnetic beam to a superficial artery structure that does not move with breath; a receiving system for receiving first reflected electromagnetic beam data from the chest and/or the abdomen and for receiving second reflected electromagnetic beam data via the redirector from the superficial artery structure; a processor unit configured for separating the first reflected electromagnetic beam data from the second reflected electromagnetic beam data based on different propagation times of the respective first and second transmission electromagnetic beams; the processor unit further configured for processing the received first reflected electromagnetic beam data to retrieve breath activity information and for processing the received second reflected electromagnetic beam data to retrieve heart activity information; wherein the apparatus further comprises the redirector for the redirecting of the second transmission beam after emission by the single radar unit.
