Motion Capture Using RFID and the Kalman Filter

Analysis of Kalman Filter-Based Localization for HIMR RFID Systems

A new paper demonstrating the power of the Kalman filter is now available.  GTPG researcher Qian Yang and coauthors use sensor-fusion data from a microwave backscatter link to demonstrate mm-scale localization of RF transponders.  This study is unique because it breaks down the individual contributions of signal strength, backscatter phase, and inertial sensor measurements to a very precise position estimation problem.  This work is an important next-step in the “holy grail” of wireless position location: precise motion-capture at a distance in 3D.

Congraduations, Jake and Emily!

Jake Smith and Emily Backer graduated with their MSEE this May.  Both helped tremendously with the microwave power transfer work in the lab, with Jake working on energy-harvesting circuits to drive sample light display and Emily designing a thin, holographic reflector arrays for high-powered sources.  Jake now joins Texas Instruments in Dallas, TX while Emily is staying local in Duluth, GA as she starts a position at ViaSat.  Congratulations on the great contributions you both made to our program as well as the new jobs with top-notch companies!

We should also note that Zach Silva successfully completed his MSEE, as noted earlier, but will be returning to GT for the PhD program in the Fall.
