Abstract
Various devices, systems and methods for performing targeted sleep tracking are presented herein. Multiple digital radar data streams from multiple antennas may be received. A direction optimization process may be performed to determine a first weighting and a second weighting. The first weighting may be applied to a first digital radar data stream. The second weighting may be applied to a second digital radar data stream. The weighted first digital radar data stream and the weighted second digital radar data stream may be combined to create a first directionally-targeted radar data stream. A sleep analysis can be performed based on the first directionally-targeted radar data stream. Sleep data may be output for a user based on the performed sleep analysis.
