RATRASCmovingtagSubmitted. It is demonstrated that the quite common scenario of a moving tag can be advantageously exploited to greatly improve the reliability of the tag detection. The proposed reading procedure is based on the Inverse Synthetic Aperture Radar processing. The detection scheme relies on the integration of multiple received signals coming from the tag travelling along a known path. Remarkably, the moving scenario benefits also from the possibility to preemptively store the background echo of the environment where the tag is embedded in. This technique greatly enhances the detection probability in realistic scenarios subjected to a high clutter. Successful experimental tests of tag readings with low Signal to Noise Ratio (SNR) are illustrated.
