This article is devoted to passive submarine target motion analysis (TMA) from data given by sonobuoys and vertical arrays. The set of sonobuoys provides the time difference of arrival measurements and the vertical antennas provide cosines of elevation. The originality of this study comes from the fact that: 1) the measurements are in a cluttered environment; 2) the elevations are those of direct and/or reflected paths; and 3) the sound travel time (also called propagation delay) is taken into consideration. The asymptotic performance is evaluated by the Cramér–Rao lower bound (CRLB) and confirmed by intensive simulations.
