Abstract
Summary
Vector acoustic full waveform inversion (VAFWI) directly inverts vector data consisting of pressure and particle displacement components in the acoustic formulation. This allows us to take advantage of the directional information contained in the vector data at the cost of conventional full waveform inversion (FWI). We connect VAFWI gradient calculation to inverse wavefield extrapolation and show that this results in preservation of the low frequency content of the data during the inversion, and increase in image resolution compared to the conventional FWI.
