摘要: We develop a method for the joint inversion of noise correlation functions distribution sources and Earth structure. The forward problem is free assumptions required to equate correlations with Green allows us compute inter-station arbitrary distributions in space time. Using adjoint techniques, we design an iterative scheme structure based on waveform energy differences as misfit functional. Starting from initial model wave equation traveltime inversion, recover target velocity high accuracy. A key prerequisite good inference source distribution.
