Experimental Verifying of Acoustic Impedance Inversion

摘要

Experiments were performed to verify the validity of our strategy to improve numerical stability on impedance inversion and investigate the influence of different extracting impulse response on the inversion. The acoustic impedance profiles are reconstructed from impulse responses, the results identify to sample data or handbook data with high precision. It is shown that our algorithm is effective in practice and the inverted impedance is less dependent on the methods of extracting the impulse responses.
