Abstract
Inversion methods for estimation of geoacoustic model parameters often use the scattered field data for obtaining the properties of viscoelastic layered media. This work presents a method to retrieve ground properties information using the outdoor acoustic–seismic transfer function (admittance). The resonance method developed in A. Nagle, H. Uberall, and K‐B. Yoo [Inverse Prob. 1, 99–110 (1985)] is extended and used for a preliminary estimation of a set of parameters for a three‐layered ground model. The least squares method is used afterward to choose the model with the best fit to experimental data. Results of the reconstruction show good agreement with the experimental data. A description of the resonant technique and the experimental setup are presented. The effect of a finite size of sound source on the acoustic–seismic transfer function is also discussed.
