Zusammenfassung
Locating mobile terminals is an important requirement not only for offering location based services but also for handling emergency cases of nonsubscribed users, and radio surveillance. We propose a blind localization approach which takes advantage of multipath propagation by using additional information about the known locations of the main scattering objects, e.g. buildings. This information is processed by means of a simple ray tracing technique based on a 2D geographic data base. We assume a single observation station equipped with multiple antennas which is able of estimating the directional and relative temporal structure of the received multipath components. Exploiting the parameters of the multipath components we propose a mobile terminal tracking algorithm based on particle filtering technique.
