In view of the difficult problem of high-precision bottom detection in multi-beam shallow sea topographic survey, a multi-beam seabed detection technology based on multi-split beam phase difference is proposed in this paper, and the realization method of this detection technology under U-shaped acoustic array is emphatically discussed. The simulation and actual measurement results show that the technology is not only capable of detecting the seabed in both mirrored and non-mirrored regions, but also can improve the detection performance of the system due to the introduction of multi-split beam, phase slope error curve and image transformation.
