The Impact of Low Frequencies in Optimization and Inverse Scattering Based Wavefield Inversion

Full wavefield inversion of seismic data has a less than stering reputation as a process for direct Earth model estimation. One reason for this reputation is the absence of low frequencies in observed seismic data. In this presentation we discuss the theoretial aspects of this issue and provide empirical evidence of its validity. We further discuss this dearth of low frequencies and its relation to inverse scattering based inversion.
