On Measuring Doppler Shifts between Tags in a Backscattering Tag-to-Tag Network with Applications in Tracking

In this paper, we present a technique whereby passive tags can track each other in a backscattering tag-to-tag network (BTTN). In such a network, passive tags without any on-board radio transceivers communicate directly with each other by backscattering an external excitation signal. First, we expla…
