  abstract = {{A} geoacoustic inversion scheme based on a double beamforming algorithm in shallow water is proposed and tested. {D}ouble beamforming allows identification of multi-reverberated eigenrays propagating between two vertical transducer arrays according to their emission and reception angles and arrival times. {A}nalysis of eigenray intensities yields the bottom reflection coefficient as a function of angle of incidence. {B}y fitting the experimental reflection coefficient with a theoretical prediction, values of the acoustic parameters of the waveguide bottom can be extracted. {T}he procedure was initially tested in a small-scale tank experiment for a waveguide with a {P}lexiglas bottom. {I}nversion results for the speed of shear waves in {P}lexiglas are in good agreement with the table values. {A} similar analysis was applied to data collected during an at-sea experiment in shallow coastal waters of the {M}editerranean. {B}ottom reflection coefficient was fitted with the theory in which bottom sediments are modeled as a multi-layered system. {R}etrieved bottom parameters are in quantitative agreement with those determined from a prior inversion scheme performed in the same area. {T}he present study confirms the interest in processing source-receiver array data through the double beamforming algorithm, and indicates the potential for application of eigenray intensity analysis to geoacoustic inversion problems.},
