By using iterative improvement, one solves the seismic inverse problem. In other words, the imaging of seismic data requires a model of seismic velocity. Initially, a model of smoothly varying velocity is used. If the resulting image is not satisfactory, the velocity model is adjusted and a new image is formed. This process is repeated until a satisfactory image is obtained. In summary, iterative improvement is a means of adjusting the velocity function until, one hopes, an excellent subsurface image of the geology is obtained.
