1. A method, comprising:
pre-defining a plurality of activities associated with sleep to be detected in an interior room, 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;
forming a virtual array with a plurality of transmit and receive antennas;
beaming with the virtual array, a plurality of radar signals into the interior room;
receiving with the virtual array, radar data including a plurality of radar reflections corresponding to the plurality of radar signals;
processing the plurality of radar reflections to form a plurality of processed radar signals, the processing including noise removal and feature extraction; and
determining, with a graphical processing unit, 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
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.
