Abstract
A method serves for imaging polarimetry. A chipless, passive transponder which has a plurality of surface regions with different polarimetric properties is illuminated fully polarimetrically by radar radiation. At least one polarization-encoded image of the transponder is generated using the radar radiation reflected thereby, and the different surface regions of the transponder in the polarization-encoded image can be recognized by their at least one polarimetric property. The passive, chipless transponder has at least two surface regions with different polarimetric structures.
