 Title Full waveform inversion with interferometric measurements Publication Type Tech Report Year of Publication 2014 Authors Rongrong Wang, Ozgur Yilmaz, Felix J. Herrmann Number TR-EOAS-2014-5 Publisher UBC Keywords FWI Abstract In this note, we design new misfit functions for full-waveform inversion by using interferometric measurements to reduce sensitivity to phase errors. Though established within a completely different setting from the linear case, we obtain a similar observation: the interferometry can improve robustness under certain modeling errors. Moreover, in order to deal with errors on both source and receiver sides, we propose a higher order interferometry, which, as a generalization of the usual definition, involves the cross correlation of four traces. A proof of principle simulations is included on a stylized example. URL https://www.slim.eos.ubc.ca/Publications/Public/TechReport/2014/wang2014SEGfwi/wang2014SEGfwi.html Citation Key wang2014SEGfwi
