Abstract
Sound speed profile estimating based on the travel time of sound propagation is widely used. However, in practical applications, the measurement data often have some error from technical or human aspects. That would make adverse effects on the inversion results. Data assimilation methods were studied in this paper. Based on the uncertainty of acoustic measurement and acoustic propagation model, one sound speed profile data assimilation processing system with a three-dimensional variational algorithm was established. And the sound speed profile correction results show that data assimilation could give a more accurate estimation of sound speed profile results.
