Abstract
Systems and methods for detecting biometrics using a life detecting radar are disclosed. Life detecting radars can include transmit antennas configured to transmit continuous microwave (“CW”) radio signals that reflect back upon making contact with various objects. The signal can be systematically varied in frequency to provide a signal that is essentially continuous with short gaps between transmissions at different frequencies. The reflected return signals are received by one or more receive antennas and processed to detect one or more targets. The received signal can include a static (i.e. constant phase) signal corresponding to reflections from objects that do not move. The received signal can also include a phase varying signal that corresponds to reflections from a living target having measurable biometrics including (but not limited to) breathing patterns and heartbeats. Clutter can be removed and the remaining portions of the received signal are analyzed for target detection.
