Ultra high energy (UHE) particles of cosmic origin impact the lunar regolith and produce radio signals through the Askaryan effect, signals that can be detected by Earth based radio telescopes. We calculate the expected sensitivity for observation of such events at the Giant Metrewave Radio Telescope, both for UHE cosmic rays (CR) and UHE neutrino interactions. We find that for 30 days of observation time a significant number of detectable events are expected, above 10(20) eV, for UHE CR or neutrino fluxes close to the current limits. Null detection over a period of 30 days will lower the experimental bounds by a magnitude competitive with both present and future experiments at the very highest energies.
