Sensor radars enable new important applications. Their localization capability is challenged by wireless propagation conditions, which can be mitigated by employing diversity techniques. We introduce subset diversity (SSD) radars that exploit diverse spatial and temporal propagation conditions for the selected sensors measurements. A framework for analysis and design of SSD sensor radars is developed, jointly considering (i) network setting, (ii) propagation environment, (iii) sensor measurements, and (iv) localization techniques. As a case study, we consider ultrawide bandwidth (UWB) sensor radars with subset diversity in a typical indoor environment. Results enable a clear understanding of how network setting affects the passive localization performance.

Abstract

Sensor radars enable new important applications. Their localization capability is challenged by wireless propagation conditions, which can be mitigated by employing diversity techniques. We introduce subset diversity (SSD) radars that exploit diverse spatial and temporal propagation conditions for the selected sensors measurements. A framework for analysis and design of SSD sensor radars is developed, jointly considering (i) network setting, (ii) propagation environment, (iii) sensor measurements, and (iv) localization techniques. As a case study, we consider ultrawide bandwidth (UWB) sensor radars with subset diversity in a typical indoor environment. Results enable a clear understanding of how network setting affects the passive localization performance.
