TAROGE is an antenna array on the cliff of Taiwan’s east coast to monitor ultra-high energy cosmic rays (UHECR, > 10^19 eV). The antennas face the Pacific Ocean to detect radiowave signals emitted by the UHECR-induced air shower. The unique terrain of TAROGE site allows the antennas to collect both the direct-emission and the ocean-reflected radiowave signals induced by UHECR. So far two TAROGE stations have been deployed. The second TAROGE station (TAROGE-II), which consists of 6 dual-polarization log-periodic dipole antennas (110-500 MHz), was installed on the 1100 m elevation near TAROGE-I in December of 2016. In this report, we introduce the basic concept of TAROGE, its data tacking, expected sensitivity, and future prospect.
