Consider the problem of joint state estimation and mode identification for over-the-horizon radar (OTHR) multipath target tracking, where multiple resolvable detections corresponding to the different propagation modes come from the same target, a consensus based distributed expectation-maximization (EM) framework is proposed in this paper. By regarding the OTHR as a sensor network where each propagation...
We propose a novel distributed generalized expectation maximization (EM) method for non-cooperative target localization using a wireless sensor network. We consider the scenario where few or no sensors receive line-of-sight signals from the target. Each sensor is able to measure the time difference of arrival of the target's signal with respect to a reference node, as well as the angle of arrival...
