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.

Fall detection systems and methods use radar chips to scan monitored regions such that data obtained by the scanning radar chip are processed to identify targets within the monitored region. Targets are tracked and profiled indicating their posture and fall detection rules are applied. Standard energy profiles and time dependent energy profiles are generated for various segments of the monitored region and compared to the current energy profile for each target segment of the monitored region. Anomalies are detected, false fall alerts filtered out and verified fall alerts are generated.
