ELECTROMAGNETIC TOMOGRAPH FOR INHOMOGENEOUS MEDIA

According to an aspect of the present disclosed subject matter, a method comprising: transmitting RF-transmission-signals incorporating at least one frequency produced by an apparatus and radiated in turns by an electromagnetic aerial interface toward each plane of a plurality of planes of a surveyed media; receiving RF-signals reflected from each plane of the plurality of planes in turn by the electromagnetic aerial interface, wherein each one of the RF-signals of each plane is characterized by phases amplitudes and frequencies; assembling a three-dimensional raw data array comprised of a plurality of two-dimensional raw data arrays, wherein each two-dimensional array comprises information elements of a different plane; reconstructing an image from the three-dimensional raw data array using an RF tomography technique, wherein the image depicts morphology and properties of inhomogeneities inside and beyond the surveyed media; and filtering artifacts out of the image based-on analysis of image quality measurements.
