System and method for improved object identification
View Patent ↗A method for identifying objects within a set of objects includes the steps of transmitting a signal toward a region of interest, receiving energy reflected from the region of interest, establishing a baseline field strength for the received reflected energy, determining at least one frequency at which the field strength substantially differs from the baseline field strength for the received reflected energy, and identifying at least one object within the region of interest based upon the determined at least one frequency.
