Identification of Chipless Sensors in Cluttered Environments From 3D Radar Imagery and Polarimetry
Résumé
This paper reports a new method for the identification of
chipless sensors based on 3D radar imagery and polarimetry.
Chipless pressure sensors are wirelessly interrogated
in a highly reflective environment with a 24GHz FM-CW
radar. A novel algorithm of identification based on magnitude
of radar echoes 3D distribution is proposed and applied
to mitigate the clutter and identify multiple chipless
pressure sensors. The electromagnetic footprint of sensors
is defined and advantageously used for identification purposes.
