Abstract
Summary
Full waveform inversion has become more and more popular in both academic research and commercial production in recent years. However, the lack of low frequency and maximum offset limited its field application. In this study a new FWI method taking adaptive illumination compensation into consideration is purposed to solve the limited maximum offset problem. Two-way wave equation illumination analysis method is applied to adaptively compensate and balance the gradients. The synthetic data test shows that our method can enhance the FWI iteration converge stability in poor illuminated area and provide better image at the same time.
