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.

System and method for tracking a body

A method, system, and computer program product is provided for tracking the shape of a surface. The method includes generating a first plurality of surface models based on the surface, each surface model associated with surface parameter values and representing a different shape, determining an estimated position of the plurality of RF transponders on each surface model of the first plurality of surface models, communicating at least one activation signal to the plurality of RF transponders arranged on the surface, the surface comprising an unknown shape, receiving a plurality of response signals from at least a subset of the plurality of RF transponders, determining radio environment parameters for each surface model of the first plurality of surface models, and determining at least one selected surface model of the first plurality of surface models.
