Radar-based electromagnetic wave fall detection system

Abstract A radar-based electromagnetic wave fall detection system comprises a detector in operable communication with a radar unit and a floor vibration sensor. The detector is configured to detect a fall using signals obtained from both the radar unit and the vibration sensor, thereby improving det...
