Ultra-wideband (UWB) impulse radio is a technology ideally suited for centimeter-level localization, and especially attractive because of the possibility to employ backscattering tags which can be made energy autonomous. Still, achieving such accuracy in localizing backscattering tags is challenging and requires careful consideration in implementing the signal processing chain. This paper presents signal processing and system approaches for cm-level localization of backscattering tags in a multi-static configuration. We present results of a measurement campaign, where a backscattering UWB system provides localization with an error of 6.5 cm.

Abstract
Ultra-wideband (UWB) impulse radio is a technology ideally suited for centimeter-level localization, and especially attractive because of the possibility to employ backscattering tags which can be made energy autonomous. Still, achieving such accuracy in localizing backscattering tags is challenging and requires careful consideration in implementing the signal processing chain. This paper presents signal processing and system approaches for cm-level localization of backscattering tags in a multi-static configuration. We present results of a measurement campaign, where a backscattering UWB system provides localization with an error of 6.5 cm.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
