Accuracy studies for TDOA-AOA localization of emitters with a single sensor

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 Cramér-Rao lower bounds.
