Abstract

This paper presents a localization approach which aims to detect and localize discrete mobile scatterers. Therefore, a network of spatially distributed transmitting and receiving nodes is used. The localization problem is formulated as a non-linear optimization problem and corresponding performance bounds for the positioning error are provided. To solve the optimization problem, an iterative non-linear least squares approach is used, following the algorithm of Levenberg and Marquard. The proposed localization approach is evaluated based on wideband measurement data. It is shown, that the localization of mobile scatterers can be achieved. A further evaluation reveals a strong dependence of the localization performance on the preceding link level parameter estimation. Particularly sparse networks are shown to be sensitive to rich multipath environments.
