Indoor fall detector based on Doppler radar

A smart fall detector based on a Doppler radar is presented aiming at non-invasive fall detector in home environment. A Continuous Wave (CW) signal is used to assess the changes in speed of different persons observed during daily activities which include: falling, walking, sitting down, standing up, random movement, and no movement. The speed measurements are introduced in a machine learning methodology to estimate a generic model that discriminates fall events from normal movements.
