Target’s state can be estimated by bearings-only target motion analysis from a hiding observer. There are several methods, including regression, batch and geometric solution. Using simple mathematical calculation with diagram illustration is the advantage of the geometric method solution which replaces the calculation of their complicated motion equations. Therefore the geometric method is still using widely on board submarine of several navies. The passive target motion analysis, focus on the targets which maintain constant course and speed. The operator has to maneuver the ship, let target be observable, then one can estimate the target’s state from bearings. The better solution of target’s state can be got after doing the better own ship maneuver. This purposes of this thesis proposes with the graphical solution of Improved Ekuland Range to analysis two dimensional bearings-only target motion, and applying Monte Carlo simulation, then to obtain the optimal observer’s maneuver. The result gets better estimation of target’s state than Coll’s and Bakos’s maneuver during the target approach does.
