Abstract
A vital sign detection system includes a radar device, a nonreciprocal network, a first antenna and a second antenna. An output signal from the radar device is delivered to the first antenna via the nonreciprocal network and then transmitted to a first side of a biological subject via the first antenna. A first reflection signal from the first side of the biological subject is received by the first antenna and then delivered to the second antenna via the nonreciprocal network and then transmitted to a second side of the biological subject via the second antenna. A second reflection signal from the second side of the biological subject is received by the second antenna and then delivered to the radar device via the nonreciprocal network for vital sign detection with random body movement cancellation.
