Claim 0:
1. A monitoring device comprising:
a radar sensor;
a processing device coupled to the radar sensor; and
a memory coupled to the processing device storing computer-executable instructions that, when executed, cause the processing device to perform operations comprising:
detecting, by the radar sensor, a first set of radar signals associated with respiratory movements of at least one of a first user and a second user within a first zone comprising at least a portion of a bed;
detecting, by the radar sensor at a first time, a second set of radar signals associated with first motion of the first user in a second zone located adjacent to a first side of the bed;
detecting, by the radar sensor at a second time, a third set of radar signals associated with second motion of the first user in the second zone located adjacent to the first side of the bed;
identifying a portion of the first set of radar signals corresponding to a time period between the first time and the second time;
generating a modified first set of radar signals by removing the portion of the first set of radar signals from the first set of radar signals; and
causing generation of a sleep-related analytic associated with the first user using the modified first set of radar signals.
