1. A method for the tomographic reconstruction of a subsurface geological formation which has diffracted at least one wave of energy interacting with it, comprising the steps of:

  • (a) obtaining one or more signals which are a function of at least one of the phase and amplitude of the diffracted propagating wave after said wave has interacted with said formation;

    (b) preprocessing said obtained signals, wherein said preprocessing includes the step of scaling and phase correcting signals; and

    (c) converting said preprocessed signals by means of a filtered backpropagation technique into an array representing the partial reconstruction profile of the formation.
