Angular wavenumber

A very interesting thing I re-discovered today is the angular wavenumber. Although it seems like I had understood that pretty well long back, I had forgotten quite some things about it. The rumination came from my continuous learning process of Fourier Transform. While I seem to have gotten a hang of temporal Fourier transform, spacial … Continue reading Angular wavenumber

Brief note on seismic migration and inversion

Seismic inversion can be classified as Methods based on iterative forward modeling Methods based on downward wave field extrapolation Inversion by iterative forward modeling: Essentially in this method, elastic properties of the geological subsurface are estimated. Given the seismic source and an initial subsurface model, a seismic data is simulated. The simulated data is then … Continue reading Brief note on seismic migration and inversion
