Orientation Determination of a Scatterer Based on Polarimetric Radar Measurements
Résumé
This paper presents a theoretical model to extract the orientation of any scatterer under normal incidence. Analytical expressions are given for mono-static configuration in co-polarization and can easily be extended in cross-polarization. The proposed approach is particularly interesting to determine chipless tag orientation, i.e., to use a chipless tag as an orientation sensor. Since the method is valid for any scatterer, antenna mode do not have to be separated from the structural mode before estimation, thus the proposed approach can directly be applied on raw signal without time gating. Measurements in anechoic chamber are done to evaluate the performance of the proposed solution .
