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.
