In this paper, a novel wavelet-based detection algorithm is introduced for the detection ofchipless RFID tags. The chipless RFID tag has a frequency signature which is identical to itself.Here a vector network analyser is used where the received backscatter signal is analysed infrequency domain. Thus the frequency signature is decoded by comparing the waveletcoefficients which identifies the bits accurately. Further, the detection algorithm has beenapplied for the tag detection under different dynamic environments to check the robustness ofthe detection algorithm. The new method doesn’t rely on calibration tags and shows robustdetection under different environments and movement.
