Abstract: Aiming at the inversion problem of shallow sea sound speed profile, the sound speed profle estimation
under the thermocline condition is realized combing with intrinsic sound ray matching inversion of sound line
based on the niche genetic algorithm. The empirical orthogonal function is used to reduce the multi-parameter
uncertainty of sound speed profile. The propagation delay of the fastest characteristic sound ray obtained from
acoustic calculation model and the delay measured during ocean experiment are matched based on the niche
genentic algorithm to obtain the most accurate empirical orthogonal function estimation and achieve the sound
speed profile inversion. The ocean experiment data show that the method can effextively invert the shallow
sea sound velocity profile and the precision is better than traditional genetic algorithm invsersion results.
Keywords: Acoustic tomography; Sound speed profile inversion; Niche genetic algorithm
