摘要

A stochastic inverse method is presented to estimate the seabottom scattering coefficients on the base of shallowwater ray mode reverberation theory. The reverberation data measured in the Asian Sea International Acoustic Experiment (ASIAEX) in the East China Sea in 2001 are analysed. The seabottom scattering coefficients are estimated from the reverberation loss. The inverted results are then tested by comparing the experiment data with the predictions of the reverberation vertical correlation and the reverberation loss measured on the different sea states at the same site. The fact that the experimental data are in good agreement with the theoretical predictions indicates the validity of the estimates.
