VHF Coherent Back-scattering Ionospheric Radar
Coherent 40.8 MHz scatter radar at the low end of the VHF band was built in Daejeon city (36.18°N, 127.14°E, dip latitude 26.7°N), South Korea. This radar was installed and continuously operational since December 2009. This radar has the capability of long-term mid-latitude studies of E- and F-region FAIs in the Far East Asian sector, which has been undertaken to further investigate the characteristics in their morphology, occurrence, climatology, and persistence.
