Apparatus and process for electromagnetic imaging

At least one computer-readable storage medium having stored thereon at least one of:

• (i) processor executable instructions and (ii) gate configuration data, which, when executed by at least one processor and/or used to configure gates of a field-programmable gate array, cause the processor and/or the configured gates to execute the steps of:
• causing an array of antennas disposed about an object to emit electromagnetic waves;
• causing the array of antennas to detect the electromagnetic waves;
• capturing scattering data representing at least a two-dimensional array of measurements of electromagnetic wave scattering by internal features of the object, wherein each said measurement represents scattering of the electromagnetic waves emitted by an antenna of the array of antennas disposed about the object, as measured by the same antenna or by another antenna of the array of antennas;
• and
• processing the scattering data to generate image data representing a spatial distribution of internal features of the object, wherein the generation of the image data does not involve tomographic reconstruction but is based on a weighted mapping to directly map the measurements of electromagnetic wave scattering to a corresponding spatial distribution of electromagnetic wave scattering by the internal features of the object that corresponds to the physical shape of the object to enable the detection, localization, size estimation, shape estimation and classification of one or more features of interest of the object.
