In this paper, a new single sensor passive emitter localization approach is presented. The use of signal structure information allows TDOA-based localization with a single moving sensor node. A direct position estimation scheme is derived for the single sensor TDOA localization problem. The feasibility of the proposed method is shown in simulations. The position estimation accuracy of the single senor TDOA and the direct technique are compared. Field experiments using an airborne sensor are conducted to prove the concept.
