Abstract
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.
