Abstract

We propose to use Marchenko-redatumed Green’s functions for linearising full waveform inversion without a singlescattering approximation. While most conventional inversion strategies build on such a single scattering assumption, i.e. the Born approximation, we argue that the Marchenko equation adds value in correctly addressing and incorporating multiples in the inversion procedure. We outline the concepts of Marchenko redatuming and full waveform inversion based on the Lippmann-Schwinger integral. Furthermore, we present and discuss a first numerical study towards a linearisation of full waveform inversion via Marchenko redatuming. Our results show that incorporating Marchenko into the inversion allows for a significantly lower regularisation of the inverse problem, leading to a suppression of undesirable artefacts in the inverted models and suggesting a potentially improved stability of the newly-linearised, exact inverse problem.
