Abstract
This paper is based on the characteristics that the electromagnetic parameters of the RFID antenna will change with its size. Based on the USRP and GNU Radio platform, the RFID signal's detection method of the signal source frequency and the direction of arrival RFID signal are proposed in the paper. The specific algorithm includes the periodic graph method for the spectrum analysis of the signal and the spatial spectrum and DOA estimation algorithm based on one-dimensional array received signal model to detect the direction of the signal, as experimentally verified in the paper.
