Embodiment Construction
[0035] Below in conjunction with accompanying drawing and embodiment the present invention will be described in further detail:
[0036]With reference to Figures 1-2, in the sound velocity profile inversion method described in the present invention, multiple buoys are used in combination as a receiving system for acoustic signals. Assume that four buoys are respectively deployed on the sea surface, and their positions form a square. A short vertical receiving array is connected below each buoy, and each vertical array contains N=5 receiving hydrophones of different depths. A heavy hammer is hung at the bottom of the vertical receiving array. Because the buoys can float freely on the sea surface, the receiving array is a short vertical array, and the deployment depth in sea water is not large, so the receiving array can basically maintain a vertical state. The horizontal position of the point is the same as the position of the buoy, which can be obtained through the GPS receiv...
