Abstract
(ACM). In many applications, we have to identify an object and then locate the object to within high precision (centimeter- or millimeter-level). Tracking mobile RFID tags in real time has been a daunting task, especially challenging for achieving high precision. We achieve these three goals by leveraging the phase value of the backscat- tered signal, provided by the COTS RFID readers, to estimate the location of the object. To illustrate the basic idea of our system, we firstly focus on a simple scenario where the tag is moving along a fixed track known to the system. We propose Differential Aug- mented Hologram (DAH) which will facilitate the instant tracking of the mobile RFID tag to a high precision. We then devise a com- prehensive solution to accurately recover the tag's moving trajec- tory and its locations, relaxing the assumption of knowing tag's track function in advance.
