Weighting Schemes for the Frequency-Domain Waveform Inversion

Expanded Abstract for SEG Annual Meeting !!


We present a seismic waveform inversion using a weighting function. With the assumption that the source wavelet can be sufficiently estimated, we define the objective function as the L2-norm of the difference between the Green’s functions. We show the spectral analysis of the scaled gradient and use numerical examples to show that weighting can improve the inversion result.
