 A method of interpolating wavelet multirescale inversion (IWMI) based on interpolating wavelet transform (IWT) is first proposed to inverse seismic waveform. The problem is solved in multiresolution interpolating space rather than traditional physical space. The stability of modeling, local minima, computational burden and perturbation of optimization parameters can be improved effectively due to the properties of the interpolating wavelet. It is a promising method because of its low dependence on the initial model, convergence efficiency and robustness. Numerical results show the effectiveness and potential of the method.
