Accuracy studies for TDOA-AOA localization of emitters with a single sensor
Résumé
This paper investigates the problem of source localization
using a single sensor and multipath signals in a
electromagnetic warfare (EW) context. Time difference of arrival
(TDOA) and angle of arrival (AOA) measurements are used
to localize transmitters. This approach is interesting in the
sense that no a priori knowledge of scatterers is required. For
this localization approach, the minimal number of components
(emitters and reflectors) is determined. Attainable accuracies of
our method for the different possible configurations are discussed
using the Cram´er-Rao lower bounds.
