Hybrid source localization methods have proved to be able to improve the accuracy of position estimation. But several existing hybrid algorithms deal with two-dimensional (2D) scenarios only or require numerical search. This paper introduces a three-dimensional (3D) passive localization method using the active time of arrival (TOA) measurement and the one TOA and two angle of arrival (AOA) pairs observed at two stations. A closed-form solution is derived for the 3D source location with hybrid measurements from two stations. The experimental results demonstrate that the proposed method outperforms the state-of-art ones in terms of root mean-square error (RMSE), especially in large measurement error situation.
