Claim 14:
15. A system, comprising:
a virtual array with a plurality of transmit and receive antennas;
at least one processor communicatively coupled to the virtual array; and
a memory device having stored thereon instructions to cause the at least one processor to execute a method comprising
pre-defining a plurality of activities associated with sleep to be detected in an interior region, the activities based on sleep motion and vital signs, the sleep motion including tossing and turning;
determining a model for each predefined activity based on recorded activity data in a plurality of locations;
causing the virtual array to beam a plurality of radar signals into the interior region
and receive reflections corresponding to the plurality of the radar signals;
processing the plurality of radar reflections to form a plurality of processed radar signals including noise removal and feature extraction;
determining at least one activity from the plurality of pre-defined activities associated with sleep by matching the plurality of processed radar signals with one of the determined models via pattern matching; and
providing a behavioral feedback to an individual in response to the determined at least one activity, wherein the feedback modifies a pre-sleep behavior of the individual that affects the sleep of the individual when the behavioral feedback is followed by the individual, resulting in an improvement of the sleep of the individual.
