AbstractNear-surface imaging structures often plays a significant role in the field of environmental and engineering geophysics. Early-arrival waveform inversion (EWI) is state-of-the-art method to imaging near-surface structures due to its high resolution. However. the method faces with cycle-skipping issue which might lead to an unexpected local minimum. https://www.alarecre.com/NFL-Atlanta-Falcons-Double-Vision-iPhone-13-Pro-MagSafe-Case-p92343/
