Abstract

Systems and methods for monitoring life signs in a subject. A radar unit comprising generates raw data and a processor unit receives raw data and identifies oscillating signals in a series of arrays of complex values representing radiation reflected from each voxel of a target region during a given time segment. A phase value is determined for each voxel in each frame and a waveform representing phase changes over time for each voxel is generated. Voxels indicating an oscillating signal are selected and life sign parameters are extracted.
