| description | This paper extends the finite-difference contrast source inversion method
to reconstruct the mass density for two-dimensional elastic wave inversion in the
framework of the full-waveform inversion. The contrast source inversion method
is a nonlinear iterative method that alternatively reconstructs contrast sources and
contrast function. One of the most outstanding advantages of this inversion method
is the highly computational efficiency, since it does not need to simulate a full forward
problem for each inversion iteration. Another attractive feature of the inversion
method is that it is of strong capability in dealing with nonlinear inverse problems
in an inhomogeneous background medium, because a finite-difference operator
is used to represent the differential operator governing the two-dimensional elastic
wave propagation. Additionally, the techniques of a multiplicative regularization
and a sequential multifrequency inversion are employed to enhance the quality of
reconstructions for this inversion method. Numerical reconstruction results show
that the inversion method has an excellent performance for reconstructing the objects
embedded inside a homogeneous or an inhomogeneous background medium. |
