The middle and upper atmosphere radar of Radio Atmospheric Science Center, Kyoto University, is now partly in operation. The facility will be complete in 1985. The active array antenna system of the radar makes it possible to steer the radar beam in an interpulse period, i.e., 400 μs. The antenna system consists of independently operative subgroups, each having 19 Yagis. We expect various sophisticated experiments by the system. A preliminary observation was successful to elucidate atmospheric motions during typhoon 5 which approached the radar site in August, 1983.
