Radio detection of Ultra High Energetic Cosmic Rays and Neutrinos (UHECRv) which hit the Moon has been investigated in recent years. In preparation for near-future lunar science missions, we discuss technical requirements for radio experiments onboard lunar orbiters or on a lunar lander. We also develop an analysis of UHECRv aperture by including UHECv events occurring in the sub-layers of lunar regolith. It is verified that even using a single antenna onboard lunar orbiters or a few meters above the Moon's surface, dozens of lunar UHECRv events are detectable for one-year of observation at energy levels of $10^{18}$ eV to $10^{23}$ eV. Furthermore, it is shown that an antenna 3 meters above the Moon's surface could detect lower energy lunar UHECR events at the level of $10^{15}$ eV to $10^{18}$ eV which might not be detectable from lunar orbiters or ground-based observations.
