The paper deals with the problem of combined inversion of wave and electromagnetic fields. It is assumed that there exists the functional relation between the velocity and electric conductivity the character of which is known to us.
The distributions of velocity and conductivity in the medium under study are chosen such that the minimization process of data misfit functionals for the individual problems (acoustics and geoelectrics) could not bring to a satisfactory solution.
The complex functional containing a number of free parameters is used. Changing these parameters in the interactive regime, we manage to do away with the strong "ravine structure" of the individual functionals in the combined functional and reconstruct the distributions of velocity and conductivity in the medium under study with a good accuracy.
