We present a new technique to perform passive bistatic subsurface radarprobes on airless planetary bodies. This technique uses the naturally occurringradio impulses generated when high-energy cosmic rays impact the body'ssurface. As in traditional radar sounding, the downward-beamed radio emissionfrom each individual cosmic ray impact will reflect off subsurface dielectriccontrasts and propagate back up to the surface to be detected. We refer to thistechnique as Askaryan radar after the fundamental physics process, the Askaryaneffect, that produces this radio emission. This technique can be performed froman orbiting satellite, or from a surface lander, but since the radio emissionis generated beneath the surface, an Askaryan radar can completely bypass theeffects of surface clutter and backscatter typically associated withsurface-penetrating radar. We present the background theory of Askaryansubsurface radar and show results from both finite-difference time-domain(FDTD) and Monte Carlo simulations that confirm that this technique is apromising planetary radar sounding method, producing detectable signals forrealistic planetary science applications.
