Electromagnetic radiography

Electromagnetic radiography operates by scanning the ground with long wavelength microwaves. According to one developer, when it is struck by this energy; the target radiates back in a particular way; exciting molecules at atomic levels. The molecules respond with spin effects that produce “a spectrographic signature of the target substance.” As noted previously, very little is known at the present time about what the limits are of this technology in terms of the operational requirements and environmental conditions for countermine applications.
