Application of the Principal Component Analysis for acceleration based UHF RFID tag tracking

An algorithm for AoA estimation of UHF RFID tags, based on an acceleration defined synthetic aperture is derived with the aid of the Principal Component Analysis. It gives an analytical solution for the tag direction and requires significantly less computational effort than comparable algorithms while performing nearly as good as the benchmark algorithm. Handheld tracking systems using the proposed algorithm could therefore be implemented with significantly higher cost and power efficiency.
