Abstract: An athlete monitoring system includes body position beacons, a localized radar system, a foot force detection system, and a processing module. The beacons are positioned at various locations on the body of the athlete. The localized radar system creates a localized radar coordinate system in which the athlete is positioned and, at a first sampling rate, produces frames of body position data based on determining location of the beacons within the localized radar coordinate system. The foot force detection system generates frames of left foot force data and frames of right foot force data. The processing module correlates the frames of body position data, the frames of left foot force data, and the frames of right foot force data to produce integrated ground-body interaction data and athletic movement data.
