| 内容記述 | Ham-band Radio Observation (HRO) is one of the observational techniques for the forward scatter observation of meteors. We started the observation of the daily and annual variation of sporadic meteor echoes with paired two-element loop antennas (F/B ratio is 10 dB) at the Nagano National College of Technology (Nagano, JAPAN) using the beacon signals at 53.750MHz, 50W from Fukui National College of Technology (Sabae, Fukui, JAPAN) from Aug.2000. The direction of one of this paired antenna was west toward Sabae and the other was east. This system could be roughly detected the direction of the radio echoes. Using this system, we observe the daily variation of sporadic meteor echoes; the echo rose from midnight with the peak coming at about 6 a.m. and decreasing to the noon, the peak echoes were observed from the West antennas at 4 a.m. and the peak from East antenna was at 10 a.m. This daily variation is interpreted as the effect of the Earth rotation and revolution around the sun and same peculiar property of forward meteor scattering observation. We also discuss the annual variation of sporadic meteor echoes. | |||||
