Claim 7:
8. A system for identifying a sleep status of a user, comprising:
a radiofrequency (RF) transceiver configured to emit a RF signal and to receive a backscattered RF signal from the user, wherein the backscattered signal measures a vital sign of the user while the user is asleep;
an audio sensor configured to sense concurrently with detection of the backscattered RF signal, an audio signal corresponding to a sound produced by the user while the user is sleeping;
a processor operatively coupled to the RF transceiver and the audio sensor; and
a memory operatively coupled to the processor storing thereon instructions to cause the processor to execute a method, the method comprising:, determining the vital sign of the user based on the detected backscattered RF signal;
identifying the sleep status of the user based upon both the determined vital sign and the sound;
identifying one or more moving objects based upon the backscattered RF signal;

extracting separate object radar data from the backscattered RF signal for each identified moving object;
identifying one of the identified one or more moving objects as the user, and
wherein identifying the sleep status of the user comprises identifying the sleep status of the user based upon separate object radar data of the one of the one or more identified moving objects identified as the user; and
providing a feedback to the user based on the sleep status, wherein the feedback improves a sleep of the user.
