“…Therefore a local minimum of the likelihood functional cannot exist on all the correspondingX domain. Note that observability is generally ensured for a leg-by-leg observer trajectory [14,15]. Further, from (24) we note that the speed of convergence of an iterative algorithm is proportional to P p k=1 r k =r k (ˆk ¡¯k) sin(ˆk ¡¯k).…”

“…Consider, first, a two-leg path of the source. Opposite to the case of a nonmaneuvering source, two transition matrices (F 1 and F 2 ) are now required [15]. The state equations then take the following general form: …”
