Superresolution With the Zero-Phase Imaging Condition
Sarah Greer, Massachusetts Institute of Technology
Seismic migration uses wavefield data from seismic experiments to produce an image of the underlying structure of the Earth's subsurface. These images are defined by the imaging condition, which attempts to map recorded data to their reflection points in the subsurface. The zero-phase imaging condition involves a simple non-linear modification to the standard imaging condition that allows for the superresolution of scatterers and other simple models, which could be useful in applications such as geolocation. We introduce the new method and demonstrate its success using synthetic numerical results.
