Wireless Sensing and Identification based on RADAR Cross Sections Variability Measurement of Passive Electromagnetic Sensors
Résumé
In this paper we present the wireless measurement of various physical quantities from the analysis of the RADAR Cross Sections (RCS) variability of passive electromagnetic sensors. The technique uses a millimeter Frequency-Modulated Continuous-Wave (FMCW) RADAR for both remote sensing and wireless identification of sensors. Long reading ranges (up to some decameters) is reached at the expense of poor measurement resolution (typically 10%). A review of recent experimental results is reported for illustration purpose.
