- W1821987877 abstract "This report documents part of a planned measurement campaign in which spectrum measurements were done at different locations worldwide. The results of the KASI observatory site in Daejeon which was studied in October 2007 are presented. Measurements were carried out with professional broadband logarithmic periodic antenna connected to a Callisto spectrometer designed and built in ETH Zurich (Benz, 2004). This study provides the technical basis to decide whether it is possible to do spectroscopic measurements below 1GHz (λ > 30cm) in Daejeon. The results are presented, compared with Bleien observatory and displayed as digitally zoomed spectrums focusing on interesting frequency bands allocated for radio astronomy and other passive services. In terms of electromagnetic interference, Daejeon is worse than Bleien and thus not ideal for broadband spectroscopic solar radio astronomy observations. However, it is sufficient for small band width studies: to detect CME’s or to measure quiet solar radio flux at dedicated frequencies. Such narrow band studies would probably be no better than is already possible in Bleien." @default.
