In this paper,taking the measured error sound velocity profile as the initial guess value,the sound beam travel times and beam angle recorded by the multi-beam system and the generalized linear inversion method are used to get a sound velocity profile close to the actual sound velocity profile,and the inversed sound velocity profiles have contributed to the reduction of sound velocity profile error.The theoretic model computed results have verified the feasibility and correctness of the inversion method.
