Abstract
A system and method for tracking movement of a sports participant or a sports object associated with a sports activity, wherein in one example the system includes an article associated with the sports participant. The article provides a known spatial phase characteristic conveyed via electromagnetic energy. A receiver monitors the venue area within which the sports activity is occurring. Electromagnetic energy is received, wherein the received electromagnetic energy includes the electromagnetic energy from the article that conveys the spatial phase characteristic. The known spatial phase characteristic provided by said article is identified among the spatial phase characteristics of electromagnetic energy to locate the article. Physical movement of the sports participant is tracked by tracking the location of the article.
