%X A geoacoustic inversion method based on dispersion characteristic of normal modes is presented. An adaptive time-frequency analysis technique with a high resolution in both time and frequency domains is applied to derive the dispersion characteristic of normal modes from the broadband propagation signal. The bottom acoustic parameters are inverted by matching the calculated group delays of normal modes with the experimental data. Finally, some experimental results which could validate the inversion method are given.
