Abstract: Askaryan Radio Array ARA, a large-scale radio Cherenkov observatory whichscientists propose to develop in Antarctica, aims at discovering the origin andevolution of the cosmic accelerators that produce the highest energy cosmicrays by means of observing the ultra high energy UHE cosmogenic neutrinos. Tooptimize ARA-s angular resolution of the incoming UHE neutrinos, which isessential for pointing pack to its source, the relation between thereconstruction capabilities of ARA and its design is studied. It is found thatwith the noise effect taken into account, in order to make this neutrinoangular resolution as good as possible and detection efficiency as high aspossible, the optimal choice for ARA geometry would be the station spacing of1.6 km and the antenna spacing of 40 m.
