10. A scanning device for imaging a surface within a target region, the device comprising:
a radar unit comprising:
an array of transmitting antennas and receiving antennas arranged in a matrix of rectangular frames spaced at regular intervals;
an oscillator connected to said transmitting antennas;
a processor unit configured to receive raw data from the radar unit and operable to generate image data based upon the raw data by:
transmitting electromagnetic radiation towards a target region;
receiving electromagnetic radiation reflected by objects in the target region;
generating a three dimensional image of the target region comprising a three dimensional array of voxels, each voxel being characterized by a first coordinate, a second coordinate, a third coordinate and an associated value of amplitude of energy reflected from those coordinates; and
constructing an image matrix comprising a two dimensional array of pixels by selecting a unique energy value for each pixel characterized by the first coordinate, and the second coordinate;
a memory unit configured and operable to store the image data;
a display configured and operable to display an image representing the surface.
