2022.11.23 Radio ranging with ultrahigh resolution using a harmonic radio-frequency identification system- Hongfei Dai
The topic of this regular meeting of the research group is literature reading. Read together analysis of "Radio ranging with ultrahigh resolution using a harmonic radio-Frequency identification" published in nature electronics system ". This paper describes the importance of accurately detecting the position of specific objects in indoor environments for robot feedback control and non-invasive structural integrity monitoring applications, as well as the problems of poor accuracy and fuzzy identification of current optical and ultrasonic methods. An RFID system using 1 GHz harmonics can provide range resolution of less than 50 microns.
