Abstract
The single-receiver geoacoustic inversion attracts a great deal of interest recently. The paper focuses on the inversion based on the synthetic aperture created by a fixed hydrophone and a moving source in the presence of Doppler effect. The data received by a single hydrophone are transformed into the data received by a horizontal linear array (HLA) owing to the reciprocity theory of acoustic. The replica fields in matched field inversion (MFI) can be generated by the normal mode representation, which is modified using the waveguide Doppler-shifted horizontal wave numbers. The numerical simulations and the inversion results of the SWellEx-96 experimental data have verified the effectiveness of the improved inversion framework proposed in this paper.
