VHF Doppler radar installed at Kototabang, Indonesia. Operating frequency of the radio wave is 30.8 MHz. Peak and average transmitting power is 20 kW and 1.5 kW, respectively. The antenna is composed of a linear array of 18 three-element Yagi antennas with a total length of 117 m. The VHF radar has a capability to steer the radar beam to 9 directions between ±54° in azimuth around geographic south (126°-234°). Zenith angle of all the radar beams is set at 20°. Half-power full beam widths in azimuth and zenith directions are 12° and 40°, respectively. Details of specification of this radar are described by Otsuka et al. (2009). Otsuka, Y., T.
