Research on Multibeam Sounding Problem Based on Multimodal Analysis

In this paper, this study first obtain the relation of the seawater depth corresponding to the two adjacent lines, and further extend the coverage formula on the slope. Secondly,
$\beta$
is defined as the Angle between the normal direction of the survey line direction and the submarine slope on the horizontal surface.
$\gamma$
is an Angle between the plane vertical to the survey line direction and the submarine slope and the horizontal plane, and the relationship between
$\gamma$
and
$\beta$
is found by the method of spatial stereo geometry and spatial plane conversion. Then, through the method of spatial solid geometry and spatial plane conversion, the relationship between the slope Angle
$\Omega$
and the depth of seawater and the relationship between
$\Omega$
and
$\beta$
is found. Finally, the special value of
$\beta$
is drawn to conjecture, and then be verified by the formula derivation, thus solving the optimal case. The study on the multibeam sounding problem based on multimodal analysis shows that the fusion of multimodal data can effectively improve the accuracy and reliability of sounding results. However, further optimization of beamforming algorithms and addressing technical challenges such as data fusion are still needed to achieve more accurate measurement results and more reliable system performance.
