  The Radar Echo Telescope for Cosmic Rays (RET-CR) is a recently initiated
experiment designed to detect the englacial cascade of a cosmic-ray initiated
air shower via in-ice radar, toward the goal of a full-scale, next-generation
experiment to detect ultra high energy neutrinos in polar ice. For cosmic rays
with a primary energy greater than 10 PeV, roughly 10% of an air-shower's
energy reaches the surface of a high elevation ice-sheet ($\gtrsim$2 km)
concentrated into a radius of roughly 10 cm. This penetrating shower core
creates an in-ice cascade many orders of magnitude more dense than the
preceding in-air cascade. This dense cascade can be detected via the radar echo
technique, where transmitted radio is reflected from the ionization deposit
left in the wake of the cascade. RET-CR will test the radar echo method in
nature, with the in-ice cascade of a cosmic-ray initiated air-shower serving as
a test beam. We present the projected event rate and sensitivity based upon a
three part simulation using CORSIKA, GEANT4, and RadioScatter. RET-CR expects
$\sim$1 radar echo event per day.
