The given work deals with the problem of combined inversion of wave and electromagnetic fields. It was assumed that there exists the functional relation between the velocity and electric conductivity. However, the constants of the correlational dependence are given not precisely. The distributions of velocity and conductivity chosen such that the minimization process of data misfit functionals for the individual problems could not bring to a satisfactory solution. The complex functional containing a number of free parameters was used. Changing these parameters, we managed to do away with the strong "ravine structure" of the individual functionals in the combined functional and reconstruct the distributions of velocity and conductivity with a good accuracy.
