Abstract

We present results of the simulation of the intensity distribution of radio pulses from the Moon due to interaction of EeV neutrinos with lunar regolith. The radiation mechanism is of coherent \^Cerenkov radiation of the negative charge excess in the shower, known as Askar'yan effect. Several realistic observational setups with ground radio telescopes are considered. Effective detector volume is calculated using maximum-knowledge Monte Carlo code, and the possibilities to set limits on the diffuse neutrino flux are discussed.
