Abstract Vector hydrophone can measure energy and particle velocity at a point in space with one sensor and can estimate the bearing of target. This paper , sound pressure gradient method and acoustic intensity method and apply genetic algorithm for acoustic intensity method bearing of target are analyzed. Instable signal and intercross steady signal for upper precision through construct adaptive function and process genetic selection with construct adaptive function are abnegated. The result of computer simulation indicates the algorithm can effectively bearing of target and enhance the precision of bearing.
