The invention relates to a hydrophone direction finding method, a hydrophone direction finding device, a computer readable storage medium and computer equipment. The hydrophone direction finding method comprises the steps of: firstly, acquiring various paths of hydroacoustic signals output by a directional hydrophone array; subjecting the various paths of hydroacoustic signals to discrete Fourieroperation separately, so as to obtain each path of hydroacoustic energy spectrum corresponding to each path of hydroacoustic signal; and acquiring an azimuth value of direction finding at present according to various paths of the hydroacoustic energy spectra, wherein directivity of the directional hydrophone array covers a 360-degree hydroacoustic singal measurement range. The hydrophone directionfinding method and the hydrophone direction finding device can acquire various paths of hydroacoustic signals covering the 360-degree measurement range by means of the hydrophone array, so that the acquired hydroacoustic singal measurement range is complete without omission, the azimuth value of direction finding at present is obtained by adopting a method of acquiring the energy spectra, the anti-reverberation capability is high, and the hydrophone direction finding method and the hydrophone direction finding device are suitable for the complex underwater environments with reverberation andmultipath.
