 note = {P(論文), We have developed several new sounding modes for SuperDARN HF radars to increase operation flexibility ("Nasu" mode, etc.) as well as to obtain both higher time resolution special camping beams data and global convection patterns simultaneously ("Basyouhu" mode). Utilizing the new "Basyouhu" mode, we were able to detect, for the first time, very rapidly moving transient phenomena (about 20 km/s) passing through the SuperDARN radar's field of view without any ambiguity or uncertainty.},
