Article summary:
1. Wavefield reconstruction inversion is a recently proposed improved full-waveform inversion theory that introduces wave equation as a penalty term into the objective function to reduce the influence of local minima and increase computational efficiency.
2. This paper proposes a new penalty factor algorithm based on wave equation as an objective function under the assumptions of accurate wave equation and decoupling of simulated wavefield and inversion parameters.
3. Numerical experiments using synthetic data from the partial Sigsbee2A model show that the proposed algorithm can provide high-precision inversion results even when other information is inaccurate.
