METHOD OF REAL TIME SUBSURFACE IMAGING USING GRAVITY AND/OR MAGNETIC DATA MEASURED FROM A MOVING PLATFORM

摘要

A method for rapid real time imaging of geological formations and/or man-made objects having density and/or magnetization is described, using gravity and/or magnetic scalar and/or vector and/or tensor data measured by a moving platform. The gravity and/or magnetic field sensors may measure gravity and/or magnetic data at the at least one receiver along the survey lines by the moving platform. The recorded data may be applied as an artificial source of the potential field to generate an evolving migration (backpropagating) field, and may be applied iteratively. An integrated sensitivity of the potential field to density and/or magnetization perturbation may be calculated. A spatial weighting of at least one of the evolving migration fields may form an evolving real time holographic image. At least one desired property of the medium may be derived providing real time reconstruction of the volume physical properties of the geological formations and/or man-made objects.
