Abstract

Seismic imaging is a tool to reconstruct the sub-structure of a given ground from the data collected in a seismic acquisition. The standard technique for this purpose is called migration. This technique has resolution, i.e., the capacity to differentiate two nearby elements, limited by factors such as the size of the acquisition coverage and the frequency bandwidth of the data. As an alternative to produce higher resolution images, we used high resolution tools derived from the technique known as Multiple Signal Classification (MUSIC). In this work, we present a brief review and propose the use of the temporal variation of MUSIC (T-MUSIC) in the context of seismic diffraction imaging.
