Based on the sea dipole sound field, a single hydrophone based localization algorithm is proposed, and the signal processing flow and Hough transform method of hyperbola extraction are designed. The sea test results show that the signal processing and hyperbola extraction have higher gain, the positioning algorithm is robust and has higher accuracy. The required equipment of the algorithm is simple and the computation is small. It has the characteristics in the parameters estimation of the near-target and the radiation noise measurement.
