FMCW RFID backscatter localization

Abstract

Due to applications in supply chain management, virtual reality, and asset tracking, there has been an increasing interest in accurate localization and motion tracking using radio-frequency identification (RFID) tags. In this thesis, we explore a one-shot radio-frequency identification based localization and motion tracking approach with high accuracy, low latency, and whose cost is much lower than the current state-of-the-art. We propose an implementation that uses frequency-modulated continuous-wave radar for backscatter channel estimation. Overall, our system contributes improvements in the sampling rate and cost of the current state-of-the-art one-shot estimation systems.
