摘要：
A geoacoustic inversion method is proposed based on the modal dispersion curve of two-wideband explosive signals for range-dependent environment.It is applied to the wideband explosive sound source data from the South China Sea in 2012.The travel time differences of different modes at various frequencies and distances are extracted by warping transform.The mean bottom acoustic parameters are inverted by matching the theoretical modal time differences to that of the experimental data.The inversion results are validated by using other explosive signals at different distances.
