Claim 0:
1. A smart-home device with integrated fall detection, the smart-home device comprising:
a housing;
a speaker within the housing;
a microphone within the housing;
a monolithic radar integrated circuit that comprises an antenna array for receiving reflected radar, wherein:
the monolithic radar integrated circuit is housed by the housing; and

a processing system, comprising one or more processors, that is in communication with the monolithic radar integrated circuit, the processing system being configured to:
receive raw waveform data from the radar integrated circuit;
filter, from the raw waveform data, waveform data indicative of static objects to obtain motion-indicative waveform data;
perform center-of-mass tracking on a moving object present within the motion-indicative waveform data;
classify the moving object based on the center-of-mass tracking using a pre-trained machine learning model;
determine that a fall by a person has occurred; and
output an indication that the fall has been detected.
