Optimal Range-Difference-Based Localization Considering Geometrical Constraints

Bishop, Adrian; Fidan, Baris; Anderson, Brian; Dogancay, Kutluyil; Pathirana, Pubudu


This paper proposes a new type of algorithm aimed at finding the traditional maximum-likelihood (TML) estimate of the position of a target given time-difference-of-arrival (TDOA) information, contaminated by noise. The novelty lies in the fact that a performance index, akin to but not identical with that in maximum likelihood (ML), is a minimized subject to a number of constraints, which flow from geometric constraints inherent in the underlying problem. The minimization is in a higher...[Show more]
