Optimization techniques and inverse problems: Probing of acoustic impedance profiles in time domain

Abstract : A method of acoustic probing of an inhomogeneous plane stratified medium is discussed. The impedance profile is reconstructed from a time‐domain analysis of the pressure reflected when this medium is illuminated by a known pulse. This analysis is made from an exact integral formulation in an iterative manner by means of the optimization theory. At each step, the direct problem (scattered pressure computation) and its related adjoint problem are solved for a given impedance profile. The behavior of this probing procedure is examined particularly in comparison with known approximated techniques based on a deconvolution process.
