Abstract :
It is well known that spark transmitters can be sources of ultra-wideband (UWB) radiation. It is also known that high-voltage low energy static discharges are ubiquitous in nature, whenever there is friction between surfaces. Provided is a simple electromagnetic model and it is suggested that it is feasible to construct an ultra-wideband correlator capable of imaging a region of space containing such sources. This would permit a new window of observation on several physical processes, with applications ranging from observations of ice flows to covert operations.
