f Evaluation of the ambiguities of seismic inversion

The problem of acoustic and elastic inversion has been studied by several authors; however, there is still the need to understand completely the ambiguities of the inversion, i.e. to determine the reliability of the solution. The wavefield obtained insonifying the medium that results from the inversion will match the data, but there is no guarantee that the solution proposed is the realone. Besides, another interesting problem, not yet completely solved, is the determination of the resolution of velocity analyses, in presence of an unknown AVO.
