In addition to the target location, the turn-around times and clock skews are considered unknown. Since an optimal estimator for this problem cannot be tackled directly, we approximate it by a suboptimal, robust one, formulated as a generalized trust region subproblem. Even though nonconvex in general, exact solution of the derived estimator can be obtained by just a bisection procedure. Simulation results validate the effectiveness of the proposed technique, matching the performance of the state of the art with significantly lower computational complexity.application/pdfengopenAccessENGENHARIA ELETROTÉCNICATIME OF ARRIVALTIME OF ARRIVALELECTROTECHNICAL ENGINEERINGarticlehttps://doi.org/10.1109/LSP.2018.2810829https://www.scopus.com/record/display.uri?eid=2-s2.0-85042854949&origin=resultslist&sort=plf-f&src=s&sid=0799014e1ee5c6346b34da51fcac1995&sot=b&sdt=b&s=TITLE-ABS-KEY%28Exact+Robust+Solution+to+TW-ToA-Based+Target+Localization+Problem+With+Clock+Imperfections%29&sl=105&sessionSearchId=0799014e1ee5c6346b34da51fcac1995&relpos=0
