Two sets of the corner-reflector antenna for the observing frequencies of 30 and 60MHz were installed at Moshiri Observatory. One antenna set is directed towards the Pole-star and the other in parallel to the earth's magnetic field. An example of preliminary obsrvation results is shown.}, pages = {37--47}, title = {AN OBSEVATION SYSTEM OF COSMIC RADIO NOISE ABSORPTION BY RIOMETERS USING CORNER-REFLECTOR ANTENNAS}, volume = {30}, year = {1983} }
