Existing bearing-only localization methods do not work in the scenario that the target is above the linear trajectory of the measuring station. The Orthogonal Vector Estimator(OVE) algorithm can solve this problem while can not perform localization when only two measurements of bearings are utilized because only vectors orthogonal to the elevation plane are used by OVE. An Extended OVE(EOVE) algorithm and its transformed version based on radar coordinates system, which simultaneously utilize vectors orthogonal to the elevation plane and those orthogonal to the azimuth plane, are proposed in this paper. Simulation results reveal that proposed algorithms can work well with more accuracy when the target is above the linear trajectory of measuring stations, can also work well when there are only two measurements of bearings available.
