Abstract
Systems () and methods () for detecting a location of an EAS security tag (). The methods involve: determining a first amplitude of a response signal generated by the EAS security tag and received at a first pedestal (), and a second amplitude of the response signal received at a second pedestal (); processing the first and second amplitudes to determine whether the EAS security tag resides within a specified distance range of the first or second pedestal, a detection zone of an EAS detection system, or a backfield of the EAS detection system; issuing an alarm when the EAS security tag is determined to reside within the specified distance range of the first/second pedestal or the detection zone of the EAS detection system; and preventing issuance of the alarm when the EAS security tag is determined to reside in the backfield of the EAS detection system.
