Solving inverse scattering problems always presupposes knowledge of the incident wavefield and requires repeated computations of the forward problem, for which knowing the source term is essential. Here we present a three-step strategy to solve inverse scattering problems from total field measurements when the time signature of the source is unknown. The proposed strategy combines three recent techniques: (i) wave split-ting to retrieve the incident and the scattered wavefields, (ii) time-reversed absorbing conditions for redatuming the data inside the computational domain, (iii) adaptive eigenspace inversion to solve the inverse problem.
