The invention discloses a single-vector hydrophone subsurface buoy positioning method based on underwater acoustic communication and a subsurface buoy, and the method comprises the steps: (1), selecting a plurality of measurement points near the subsurface buoy, respectively transmitting sound signals of a specific frequency band at the measurement points, and obtaining the longitude and latitude of each measurement point; (2) the subsurface buoy receives the sound signal and obtains the three-dimensional azimuth angle of each measurement point; (3) a subsurface buoy is mapped to the horizontal plane where the measuring point is located, and a subsurface buoy mapping point P is formed; (4) respectively calculating the distance between two adjacent measuring points according to the longitude and latitude of each measuring point; (5) calculating the distance between the measuring point and the subsurface buoy mapping point P; (6) calculating an estimated coordinate of the subsurface buoy mapping point P; and (7) the estimated coordinates are multiplied by respective weights, summation is carried out, and the coordinates of the subsurface buoy mapping point P are obtained through calculation. According to the single-vector hydrophone subsurface buoy positioning method based on underwater acoustic communication, positioning is carried out in the single-vector direction, the hardware cost is low, and the positioning precision is high.
