Abstract
Provided is a system, method, and apparatus for tracking a body. The method includes communicating at least one activation signal to each RF transponder of a first array and a second array, receiving a plurality of response signals from the first array and the second array, the plurality of response signals comprising a response signal for each RF transponder of the first array and the second array, determining a difference in distances between the antenna and each RF transponder of the first array and each transponder of the second array based at least partially on at least one corresponding response signal of the plurality of response signals, and determining a relative location of the first portion of the body and the second portion of the body.
