Claim 0:
1. A method for identifying a sleep status of a user, the method comprising:
emitting a radio frequency (RF) signal, with a RF transceiver, toward the user while the user is sleeping;
receiving a backscattered RF signal, with the RF transceiver, from the user while the user is sleeping, wherein the backscattered RF signal measures a vital sign of the user while the user is asleep;
concurrently sensing, using an audio sensor, with the detecting the backscattered RF signal, an audio signal corresponding to a sound produced by the user while the user is sleeping;
identifying the sleep status of the user based upon both the measured vital sign of the user and the sound produced by the user while sleeping;
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 feedback to the user based on the identified sleep status, wherein the feedback improves the sleep of the user.
