摘要： A reader for wirelessly receiving a signal from a tag, the signal having a portion on a first side, a portion on a second side and a synchronization sequence to be detected between the first and the second side, wherein the portion on the first side, the synchronization sequence and the portion on the second side are serially arranged with each other, has a processor. The processor is configured for storing the received signal, for detecting the synchronization sequence in the received signal, for calculating a transmission characteristic between the tag and the reader, using the portion of the received signal on the first side and for extracting a payload information from the portion of the received signal on the second side, using the calculated transmission characteristic.

摘要： 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.
