Abstract

The multi-beam echo sounding system was the most effective instrument to detect the seabed topography. In order to reduce the seafloor terrain distortion caused by the representative error of sound velocity profile (SVP), the indirection adjustment inversion method was introduced after analyzing the impact of the sound profile measuring error on the seabed terrain. To testify the proposed indirection adjustment technology, two group experiments were designed, in which Group 1 used the adjustment inversion method to correct the SVP data with the small error while Group 2 utilized the same method to correct the SVP data with the large error. The results of field experimental data are shown that: the standard deviation (STD) of the inversing SVP is reduced by 64.2% and that of the single Ping seabed topographic reduce 80.7%. The computational efficiency of adjustment inversion method is better than that of the substitute SVP method. Additionally, the presented approach, which can overcome many disadvantages of the manual approach to SVP correction, is superior to that of the substitution SVP and optimizing the structure of SVP.
