【 摘 要 】

When an aircraft crashed the sound emitted by the beacon would help to detection and location the black box. While in the deep sea research, it is hardly to use the USBL, SBL and LBL as usual. In this paper a new method was introduced. In this method, the beacon could be located with only one hydrophone. The time difference of the hydrophone at different place was used to located the beacon. To verify the performance of this method, the simulation was processed. The results show that this method is effectively.
