Passive bistatic radar probes of the subsurface on airless bodies using high energy cosmic rays via the Askaryan effect [PDF]

open access: yesarXiv, 2022
We present a new technique to perform passive bistatic subsurface radar probes on airless planetary bodies. This technique uses the naturally occurring radio impulses generated when high-energy cosmic rays impact the body's surface. As in traditional radar sounding, the downward-beamed radio emission from each individual cosmic ray impact will reflect ...
