The ANITA (Antarctic Impulsive Transient Antenna) experiment may be the first experiment to identify astrophysical neutrinos of energy greater than 1018 eV. A Monte Carlo simulation has been developed to determine the sensitivity and improve the event reconstruction capabilities of ANITA at energies up to 1021 eV. Charged leptons created in charged current neutrino-nucleon interactions can produce secondary showers when they experience hard energy losses through bremsstrahlung, pair production, and photonuclear interactions as they propagate through the ice. Because the cross sections of these interactions depend on the flavor and energy of the charged lepton, the distribution of the showers can indicate the flavor and energy of the neutrino. Results from the simulation are presented.
