Long-Range Zero-Power Multi-Sensing in Industrial Environment using Polarization Diversity and 3D Radar Imagery

Abstract : This paper describes the wireless and simultaneous interrogation of multiple passive (zero-power) pressure sensors in an industrial environment with a reading range of at least 3 meters. The 3D beamscanning of the scene is performed from a 24GHz FM-CW radar and for diverse electric field polarizations. The benefits of using the cross-polarized electric fields combined with a radar imagery technique are enlightened from the analysis of the ambient clutter and the simultaneous remote interrogation of two passive pressure sensors. The measurement uncertainty on pressure obtained from the proposed long-range wireless technique is finally reported and discussed.
