Localization of radar emitters from a single sensor using multipath and TDOA-AOA measurements in a naval context

This paper investigates the problem of source location from a single sensor using direct and indirect signals in a maritime context. To localize the emitters, we propose to exploit time difference of arrival (TDOA) and angle of arrival (AOA) measurements. The proposed approach uses any a priori knowledge of the reflectors positions. However, in practice, it is necessary to solve an assignment problem. It consists in associating each pair of TDOA-AOA measurement to a given reflector, this pair being already associated to a given emitter. In order to show the potential of our approach, numerical results using simulated and real data are proposed.
