Very low frequency waves generated by lightning can be used to detect tunnels and underground structures, Map and “surf” with the precision of GPS for underground structures, invisible to the naked eye, the satellite system is for new projects, according to research by DARPA, the research agency that is part of the Pentagon.

Simply increasing prevalence, the spy satellites that can monitor even the smallest details of what happens on the accuracy of the surface, has led many countries to increase interest in building structures and underground tunnels, which can escape through observation. In more recent years, the technology used in the construction of such facilities is rapidly becoming a simple, efficient and economical.

To obtain an intelligence system that allows the verification of underground facilities, scientists and engineers from DARPA decided to focus more on the weather phenomenon: lightning, creating a large number of radio signals at very low frequency (VLF), known as “spherical” , as can penetrate deep very deep.
